The sweet potato is an important food for the population, being rich in proteins, fibers, nutrients such as K, P, Ca, Mg, Fe, Mn, Cu, and bioactive compounds. It is usually cultivated by small producers. In Brazil, the ...

Crop systems and fertilization sources can affect the chemical properties of the soil and, consequently, its fertility. With the aim of evaluating the effect of such management practices, soil samples collected at 0.0-0.10; ...

Sweet potato (Ipomoea batatas L.) is a versatile crop, but it is often grown in marginal and low-fertility areas, which reflects storage root yields far below its potential. For this reason, balanced liming and fertilization ...

Due to the expansion of the slaughterhouses sector, there is huge availability of waste from agricultural products. These waste products may be used as alternative for the production of organic fertilizers. Fertilizer ...

The objective of this work was to recommend nitrogen doses from poultry litter-based organic fertilizers in powder and pellet forms, compared with mineral fertilizer, in a high-yield corn crop under notillage. The treatments ...

The objective of this work was to evaluate the effect of the application of organomineral and mineral fertilizers to highly fertile soils on the carbon management index (CMI) and carbon fractions and stock. The experiment ...

The use of crop rotation and manure application can provide sustainability for an agricultural production system by improving soil quality and increasing nutrient use efficiency. This study aimed to evaluate the effect of ...
