Nutrient Release, Plant Nutrition, and Potassium Leaching from Polymer-Coated Fertilizer

Henrique Bley, Clesio Gianello, Lenio da Silva Santos, Lisiane Priscila Roldão Selau

09/Mar/2017

ABSTRACT The increase in food consumption and limitations in food production areas requires improved fertilizer efficiency. Slow- or controlled-release fertilizers are an alternative for synchronizing nutrient availability with the plant demands, reducing losses to the environment. The aim of this study was to evaluate the efficacy of polymer-coated KCl compared with conventional KCl. The products were incubated in soil under controlled conditions to evaluate the time required for nutrient release. A greenhouse experiment was performed with corn plants in pots […]

Characterization of soil chemical properties of strawberry fields using principal component analysis

01/Feb/2013

One of the largest strawberry-producing municipalities of Rio Grande do Sul (RS) is Turuçu, in the South of the State. The strawberry production system adopted by farmers is similar to that used in other regions in Brazil and in the world. The main difference is related to the soil management, which can change the soil chemical properties during the strawberry cycle. This study had the objective of assessing the spatial and temporal distribution of soil fertility parameters using principal component […]
