The established practices of intensive agriculture, combined with inadequate soil Κ
replenishment by conventional inorganic fertilization, results in a negative environmental …

Soil‐test correlation and calibration data are essential to modern agriculture, and their
continued relevance is underscored by the expansion of precision farming and the …

While onion cultivars, irrigation and soil and crop management have been given much
attention in Brazil to boost onion yields, nutrient management at field scale is still …

Nitrogen (N) fertilizer recommendations based on yield goals are common and do not
consider variability in soil N supply between fields. Nitrogen transformations in soils are …

Foliar fertilization is an important agricultural practice. How crop plants considerably
response to small amounts of foliar-applied minerals is not fully understood. In this study, we …

Abstract The Fertilizer Recommendation Support Tool (FRST) will perform correlations
between soil nutrient concentrations and crop response to fertilization from user‐selected …

Organic wastes (OW) are rich in nutrients, and their recycling into agriculture can substitute
chemical fertilizers. The level of substitution (partial with mineral fertilizer or exclusive with …

The optimized management of crop fertilization is very important for improving crop yield and
reducing the consumption of chemical fertilizers. Critical nutrient values can be used for …

Soil test correlation determines whether a soil test can be used to predict the need for
fertilization based on the critical soil test value (CSTV). Our objectives were to compare the …

Clay-size particles are rich in phyllosilicate minerals and iron oxides, which strongly
influence the availability of soil potassium. This study investigated the clay minerals in three …
