Four Sections, Four Crop Groups: A Regenerative Agriculture Session with the Matuber Women's Organization

AGREA Foundation and WFP convened the Matuber Women's Organization in Datu Blah T. Sinsuat for a hands-on session on field layout, crop rotation, raised beds, and organic concoctions.

The farm, divided into four

The first task was measurement. Not with surveying equipment, but by hand — pacing out the available farm area, marking it, and then dividing it into four sections.

AGREA Foundation conducted a Regenerative Agriculture Learning Session with the women of the Matuber Women's Organization in Datu Blah T. Sinsuat, Maguindanao del Norte, in the Bangsamoro Autonomous Region in Muslim Mindanao. According to AGREA's account, the women measured their available farm area by hand, divided it into four sections, and planned for four crop groups: legumes, root crops, leafy vegetables, and fruit-bearing crops.

That division is not an arbitrary exercise. It is the physical form of a principle — crop rotation — that determines whether a field stays productive or slowly exhausts itself.

Why four sections, and why those four

Crop rotation works by moving plant families around a field so that no single group draws the same nutrients from the same spot season after season. A Benguet State University technoguide on farm planning and organic management describes the practice plainly: plant four categories of vegetables in a bed — leafy, root, legume, and fruit — and rotate each category to a different subdivision every season. The same guide notes that in rotation, plant characteristics must be considered based on fertiliser use, distinguishing between crops that give nitrogen, crops that use it moderately, and heavy feeders.

The logic of the four groups is agronomic, and each group behaves differently in the soil.

• Legumes — beans, peanuts, mungbean, cowpea — fix nitrogen through their root nodules, leaving the soil richer than they found it. They are the group that pays rent.

• Leafy vegetables — pechay, kangkong, mustard, amaranth — are heavy nitrogen users, drawing on what the legumes left behind. They also occupy the ground for a short period, allowing quick turnover.

• Root crops — sweet potato, cassava, taro, ginger, turmeric — draw from different soil depths and are typically more tolerant of poorer soils. Placing them after leafy crops allows the soil to recover.

• Fruit-bearing crops — tomato, eggplant, pepper, okra — are heavier feeders with longer seasons, and are often the group most susceptible to soil-borne disease if planted in the same spot repeatedly.

The rotation is not a rule to be memorised but a sequence to be adapted. The Benguet technoguide describes the rotation as moving each category to a different subdivision every season, while a Philippine agricultural manual cited in older extension literature offers a simpler version: follow a fruit-bearing or leafy crop with a root crop, then a legume, then back to a leafy or fruiting crop.

In the session, members were divided into four groups and randomly assigned a crop category — an exercise designed to make the rotation concrete. Each group had to think through what its assigned category needed, what it would leave behind, and where it should go next. According to AGREA's account, the women experienced firsthand how crop diversification, rotation, and thoughtful field planning apply to their own farms.

Crop spacing: why the tape matters

The second element was crop spacing. The women learned that spacing depends on the type of crop planted — a point that is easy to state and consequential in practice.

Published vegetable production guides give the range. Cabbage is typically spaced at 30 centimetres by 30 centimetres in double rows. Pechay and other leafy greens are planted more densely, often 20 centimetres apart within rows. Fruit-bearing crops such as tomato and eggplant require substantially more room. The differences reflect the size of the mature plant, its root spread, and how much light and airflow it needs.

Spacing determines several things at once. It determines airflow between plants, which affects humidity in the canopy and therefore disease pressure. It determines how much light reaches lower leaves. It determines whether a farmer can walk through the plot to weed, water, and harvest without damaging the crop. And it determines how many plants a given area can support — which is, ultimately, a question about yield.

A field laid out without measurement tends to waste space on paths wider than necessary and to crowd crops that need room. The women's work of measuring and organising their farm spaces was an attempt to replace that improvisation with a plan.

Raised beds, pathways, and where the water goes

The third element was land preparation: developing raised beds and pathways that support proper water movement and irrigation.

The design principle is documented. A rotation manual for smallholder production describes low raised beds constructed with footpaths between each bed, so that the beds provide access to the crop plants and adequate drainage. Typical bed dimensions in that reference are one metre wide, ten centimetres high, and ten to twenty-two metres long.

The dimensions are not arbitrary. A bed one metre wide can be reached from both sides without stepping on it, which prevents soil compaction. A bed ten centimetres high lifts the root zone above standing water while remaining shallow enough to be built by hand. A footpath between beds carries foot traffic and, when the field slopes or the soil is heavy, carries excess water away.

For a municipality on the coast of Maguindanao del Norte, where some barangays are accessible only by boat and where water arrives on its own schedule, the question of where water goes is not cosmetic. A bed that drains is a bed where a crop does not rot after heavy rain. A path that channels water is a path that does not become a trench.

Organic concoctions: inputs from what is already there

The fourth element was the preparation of three natural farm inputs: Fermented Plant Juice (FPJ), Fermented Fruit Juice (FFJ), and Oriental Herbal Nutrient (OHN).

These are well-established preparations in Philippine organic agriculture, and the Department of Science and Technology has documented both their production and their distinct uses. DOST CALABARZON, describing a farmer training in Rizal, lists FPJ as made from vegetable trimmings, FFJ from overripe fruits, and OHN from strong-scented and spicy plants such as lemongrass and ginger. The same account sets out the uses: FPJ for plant growth and nutrient supply, FFJ for flowering and the initial bearing of fruits, and OHN to get rid of insects.

The economic logic is what makes these preparations relevant to a women's organisation. A farmer who buys synthetic fertiliser and pesticide every season must find the cash before the harvest arrives. A farmer who can produce inputs from materials already on the farm — vegetable trimmings, overripe fruit, lemongrass, ginger — has reduced that cash requirement. She has also reduced her exposure to price movements in external inputs, which in BARMM in early 2026 meant diesel rising by as much as ₱11.88 per litre and gasoline by ₱6.47 per litre in March alone.

The environmental logic is complementary. Concoctions made from farm waste and local plants recycle nutrients rather than importing them. They reduce the risk of chemical runoff. And they depend on knowledge that is already present in farming communities, even where it has been displaced by decades of promotion for purchased inputs.

According to AGREA's account, the women worked side by side, sharing tasks as they prepared all three. That detail — the sharing of tasks rather than the division of labour into one person doing the measuring and another doing the mixing — is what the organisation describes as the unity that showed throughout the session.

Where the session took place

Matuber is one of the barangays of Datu Blah T. Sinsuat, a municipality in Maguindanao del Norte with a population of 28,243 as of the 2020 Census and a poverty incidence of 48.11 per cent as of 2021. The municipality is known as the fishing capital of the province, but its local economy also rests on agriculture — rice, corn, and coconut — alongside livestock raising and local trade.

That dual character matters for what a vegetable session can accomplish. Households that fish and farm have more than one income stream, but they are also exposed to more than one kind of shock: a bad catch, a dry spell, a price collapse. A vegetable plot that produces for the household and for sale is a third stream, and one that a woman can often manage close to home.

The climate context

The session's emphasis on field planning and locally produced inputs is not happening in a neutral season.

On May 14, 2026, Chief Minister Abdulraof Macacua placed the entire Bangsamoro Autonomous Region in Muslim Mindanao under a state of calamity under Proclamation No. 0002, Series of 2026, citing the combined impact of the global oil crisis and the El Niño phenomenon. The proclamation noted that climate models projected El Niño conditions to continue until early 2027.

According to Ministry of Agriculture, Fisheries, and Agrarian Reform Minister Abunawas Maslamama, the El Niño–Southern Oscillation had already affected around 800 rice and corn farmers in Maguindanao del Sur and Maguindanao del Norte. As of April 24, about 851 hectares of farmland across 36 municipalities and 167 barangays were damaged — 537 hectares of rice and 314 hectares of corn — with losses of roughly 1,500 metric tons. Reporting in late April put the value of damaged rice and corn plantations at about ₱38.39 million.

In that context, a field that is measured and rotated, and a farm that produces its own inputs from local materials, are not stylistic preferences. They are practical measures that spread risk across more than one crop and reduce exposure to purchased inputs whose prices are set elsewhere. They do not make a farm immune to drought. They do reduce the number of ways a season can go wrong.

The partnership behind the session

The learning session is part of the continuing collaboration between AGREA Foundation and the World Food Programme, under a project funded by the Spanish Agency for International Development Cooperation.

WFP describes the project as a PHP 45 million (US$780,000) contribution from AECID to enhance agriculture-related livelihoods and boost the climate resilience of indigenous women in BARMM, reaching 28,000 people from indigenous and rural communities. Under the project, rural and indigenous women undergo training in climate-resilient agriculture and leadership skills, women's cooperatives are strengthened by linking their agricultural production to reliable markets, and activities incorporate social behaviour change to improve local food and nutrition practices.

The rationale is stated directly in WFP's announcement. Violeta Dominguez Acosta, Head of Spanish Cooperation in the Philippines, said: "If we are talking about climate resilience in a country most at risk of extreme climate, we must put indigenous women and their communities at the centre of the action."

WFP Philippines Representative and Country Director Regis Chapman framed the urgency in similar terms: "With the increasing frequency and intensity of climate emergencies in the Philippines, women are especially vulnerable. It is urgent that we strengthen their capacities and so that they can withstand shocks better."

The project's diagnosis rests on WFP's 2024 Leaving No One Behind study, which found that barriers such as climate-related risks hinder rural and indigenous women from accessing resources and decision-making processes, resulting in lost livelihood opportunities and poverty.

What the session does and does not establish

A learning session is an input. It is not evidence that the women have reorganised their fields, that they will rotate the four crop groups as planned, that the concoctions they prepared will be applied at the right concentration, that yields will increase, or that their farms will withstand the next dry spell.

Those outcomes depend on follow-through: whether the layouts fit the land and water available, whether the rotation can be maintained when a household needs a particular crop at a particular time, whether the concoction materials remain accessible, and whether the organisation reinforces the practices in the months after the session.

The honest measure is not the enthusiasm in the room. It is what appears in the following season: a plot staked into four sections, beds that drain after heavy rain, jars of fermenting preparation on a shelf, and a field that is managed according to a plan rather than improvised.

What comes next

For the participants, the next steps are concrete: stake one plot into four sections before the next planting; record which crop group went where, so that the rotation can be repeated and adjusted; prepare one concoction and observe the result on a small area; and check after the first heavy rain whether the paths are carrying water away from the beds.

For the organisation, the next step is to decide whether these practices become shared activities — a communal demonstration plot, a shared production area for concoctions, a schedule for preparing inputs together — rather than individual habits.

For AGREA Foundation and WFP, the next step is to continue the collaboration and to track whether the sessions contribute to changes in practice. That tracking should be honest about what changes and what does not.

A note of appreciation

To the women of the Matuber Women's Organization who participated: measuring a field by hand, dividing it into four, and agreeing on which crop belongs where is the least glamorous part of farming and the part that determines what the next season looks like. Doing it together is how it becomes a practice rather than a one-time exercise.
