Water Management

Our Ecosystem

At Sun Green Farms, water is not just a resource—it is a responsibility. Our water management strategy is a blend of traditional wisdom and modern ecological design. It supports our mission to build a resilient, regenerative farm that thrives in harmony with nature. With Kerala’s monsoon bringing abundant rainfall for nearly 3 to 4 months each year, currently we have designed our farm’s landscape to capture and utilize every drop in the most sustainable way possible. However, it is an evolving system and in the coming years, we may develop even more efficient methods to improve water management at our farm. Our aim is to attain an ecosystem where watering the plants and trees during summer should be minimal or unnecessary.

Harnessing the Monsoon: A Thoughtful Approach

Our farm lies on relatively flat terrain divided into three gentle levels, which helps retain water naturally. Rather than allowing rainwater to drain away into nearby paddy fields, we follow a multi-layered water conservation strategy:

Swales on Contour
Shallow, strategically placed swales along the contours of our land intercept rainwater and slow its flow, encouraging percolation into the soil.
Percolation Pits
Dug at regular intervals along the swales, these pits help further trap and absorb water, enhancing groundwater recharge.
Three-Step Pond System
Excess water from swales and flat land areas flows into three interconnected ponds. These serve as seasonal water storage units, supporting crop irrigation and maintaining soil moisture during drier months.

Preventing Soil Erosion

To ensure that water exiting the farm does not carry away fertile topsoil, we’ve constructed a canal system with stone and tile paving. This directs water overflow gently toward the downstream paddy fields, preserving soil integrity and supporting neighboring agriculture. We also grow plants with thick and bushy root systems which can hold the soil from getting washed away. The grass grown in the land is not uprooted but cut and maintained so that the roots of the grass hold the soil intact in the land without much soil disturbance during summer and rainy season.

Mulching

Good dry mulching is provided for plants and trees so that water is not evaporated during summer. It is said that plants and trees do not need frequent watering to live but only the moisture in the soil. Soil should be protected from direct sunlight, rain and wind so that no top soil and the moisture it holds is lost. Providing live mulch cover on the entire land helps preserve a significant amount of water in the soil during summer and also provides us with extra produce from the live cover creepers like pumpkin, water melon, ground nut, peas and ash gourd.

Nature’s Gift: Reverse Seepage

One of the unique benefits of our farm’s location is its proximity to the paddy fields. During the winter and early summer, we benefit from natural reverse water seepage — where moisture from the saturated paddy fields migrates back into our land through the soil. This slow natural movement of water helps maintain subsoil moisture levels even in dry conditions.
