Abstract

Soil health is determined by a set of highly correlated and interdependent physical, chemical and biological properties. Organic matter is the soul of the fertility and productivity, without which the soil is lifeless. The cost of mulberry leaf production is increasing every year because of the requirement of high and costly chemical inputs. Approximately 60% of the total cost of leaf production is accounted for the consumption of costly chemical fertilizers and farm yard manure. These inputs are becoming costlier day by day due to escalating price and are also becoming scarce. Nitrogenous fertilizers are used excessively in many crops in the country. Nitrogen (350 kg/ha/year) requirement for mulberry cultivation leads to increased cost of production. Further, the required type and quantum of fertilizer often may not be easily available to the small farmers. So, in the view of avoiding the application of single source of chemical fertilizers we have applied the different organ

Conclusion

Vermicompost used in the study in comparison to conventional organic manures supplemented with chemical fertilizers or standard package of practice, normally possesses higher levels of plant-available nutrients, particularly nitrogen and phosphorus. We probably be surprised at how dense vermicompost is, thanks to its impressive water retention capabilities. In southern dry zone areas of Karnataka with depleted – or depleting – water sources and/or soil heavy in sand or clay, adding vermicompost and other organic manures to the soil will help keep the water in the soil and conserve that precious resource. Vermicompost and other organic manures can be a thriving microbial community, full of beneficial fungi and bacteria that aid in soil health. Healthy soil is said to consist of around 5% organic material, but in over-farmed soil, that number has fallen to 1%. Introducing vermicompost and other organic manures supplemented in this study can help restore that balance
