The action of expanding and contracting as the granules absorbs and releases moisture during the helps loosen the soil, which improves in aeration making oxygen available to the plant.
Farmers can save half of the water and labour by As drought ravages the country with deadly consequences, it is emerging that a technology that could help plants live through a dry spell is sparsely in use.
Slow release fertilizers were introduced in Kenya three years ago but their uptake has been as slow, a development Bell Chemicals sales manager Jean Njiru blames for relatively new technology in Kenya is helping small-scale farmers efficiently utilize dwindling water resources to grow their crops.
These farmers are now able to cultivate crops without having to worry about the unpredictable rainfall patterns.
