Abstract The chapter highlights the potential benefits associated with the use of insect-rearing residues as biofertilizers while exploring the mechanisms by which chitin in insect frass might control common crop pathogens. The potential benefits for soil fertility derived from the use of insect frass, comparison of quality of insect-derived biofertilizers and common organic and inorganic fertilizers and insect frass and plant health improvement are discussed. While more research is essential to understand the true value of insect-derived biofertilizers for plant and soil health, preliminary findings suggest there are significant opportunities for beneficial impacts in agriculture and horticulture to be realized.

One of the mountains known as active volcanoes in the world was Merapi volcano. From the very active impact of Merapi activity, there was a continuous addition of volcanic material associated with soil fertility, which can be evaluated using the Soil Fertility Evaluation (SFE) system. This study aims to obtain a more adaptive SFE system to the southern slopes of Merapi volcano by modifying the FAO- UNESCO version of SFE system that still uses linear equations. In this research used system of quadratic equation, use of natural logarithm (ln), and modification of new parameter. From the evaluation of soil fertility is then connected with the production component of paddy rice (dry grains crop). There were several indicators that used to see the quality of the model or test the goodness of fit of the model we make, for example from its R2. In this study the quality of a model was seen from: Akaike Info Criterion (AIC) and Schwarz Criterion (SC), and the data was done by using EViews 9. The results showed the parameters that influence big in the model can be seen from the correlation and influence the parameters in single. Quadratic equations can improve the quality of a model over a linear equation. The standard SFE model which is modified by using the nat
