Climate protection starts with soils! ??betterSoil for a better world!
Humus increases the impact of filtering and buffering in soil. It has a sponge-like structure that leads to decontamination of soil. This leads to clean groundwater. A wonderful property of humus is its potential to store more water, which considerably can contribute to increase resiliency in drought periods.
Humus benefits water in agriculture
Humus protects soil against extreme temperatures. It means soil rich in humus does not get to higher temperature in summer that disturbs life in soil. Humus also protects soil pH and buffers the soil acidity and alkalinity. This allows soil particles to stay together and have strong interaction with roots of plants and trees.
Humus prevents soil degradation and stores water
Soils rich in humus increase water absorption capacity. Humus gives soil the opportunity to improve its porous structure as well as quickly absorb water. There are 600 earthworms per m2 in a soil containing proper amount of humus. This m2 can absorb 150 liters of water per hour. Humus increases water holding capacity. The greater the water holding capacity of soil is, the healthier the plant will grow and the safer the corresponding yield of crops becomes. In this regard, per 1% increase in humus content, 400 m3 additional water can be stored.
