Bioslurry is used to improve soil fertility, soil structure, and crop productivity, and it can be an excellent fertilizer.
Bioslurry contains phosphorus, potassium, zinc, iron, manganese and copper, of which the latter has become a limited factor in many soils. Bioslurry can be used to build healthy fertile soils for crop production. Indeed, bioslurry form and content stabilises with double nitrogen content, which is different from Farmyard Manure (FYM). Furthermore, the quantity of the bioslurry is also higher than regular FYM. Bioslurry contains readily available plant nutrients and higher amounts of nutrients, micronutrients than FYM and composted manure. The effects of bioslurry application are comparable to the effects of the application of chemical fertilisers.
The bioslurry can be applied:
(1) as a foliar fertiliser, being sprayed onto the crops;
(2) in liquid form (diluted) onto the roots or;
(3) in dry and composted form (combined with irrigation techniques so
that crops have sufficient water).
Bioslurry is an easily available form of compost compared to traditional compost. It is also attractive to mix with vegetative waste compost. A family owning a biogas plant will have the additional advantage, next to clean and cheap biogas, of a continuous and readily available supply of high quality fertiliser for crops
