4. Calcium and Magnesium Released from Residues in an Integrated Crop-Livestock System under Different Grazing Intensities
ABSTRACT Under integrated crop-livestock production systems (ICLS), plant and animal residues are important nutrient stocks for plant growth. Grazing management, by affecting the numbers of both plants and animals and the quality of residues, will influence nutrient release rates. The objective of this study was to evaluate the impact of grazing intensity on

6. Calda sulfocálcica em pomares de citros: evolução da resistência em Brevipalpus phoenicis (Acari: Tenuipalpidae) e impacto sobre Iphiseiodes zuluagai (Acari: Phytoseiidae) / Lime sulfur in citrus groves: resistance evolution in Brevipalpus phoenicis (Acari: Tenuipalpidae) and impact on Iphiseiodes zuluagai (Acari: Phytoseiidae)
The use of the lime sulfur as an alternative product for controlling Brevipalpus phoenicis (Geijskes) has intensified in Brazilian citrus groves. The lime sulfur is the only efficient product used to control B. phoenicis and certified by organic producers with an average of 11 sprayings per year. Due to intense use of this product, the major objectives of th

12. Ferritin reactions: Direct identification of the site for the diferric peroxide reaction intermediate
Ferritins managing iron–oxygen biochemistry in animals, plants, and microorganisms belong to the diiron carboxylate protein family and concentrate iron as ferric oxide ≈1014 times above the ferric Ks. Ferritin iron (up to 4,500 atoms), used for iron cofactors and heme, or to trap DNA-damaging oxidants in microorganisms, is concentrated in the protein nan
