Municipal solid waste compost amendment in agricultural soil: changes in soil microbial biomass
Agricultural application of Municipal Solid Waste (MSW), as nutrient source for plants and as soil conditioner, is the most cost-effective option of MSW management because of its advantages over traditional means such as ...
The Effect of Humic Substances and Phosphate Fertilizer on Growth and Nutrient Uptake of the Potato
The use of applied phosphorus (P) and the uptake of nutrients from the soil by plants can be improved when the fertilizer is combined with the application of humic substances (HS). However, these beneficial effects are ...
Nutrientes no solo e na solução do solo na citricultura fertirrigada por gotejamento
Soil solution analysis has shown to be a promising method for soil fertility diagnosis, mainly in fertigation systems. The objective of this study was to evaluate the behavior of nutrients in soil and soil solution by ...
Potassium Leaching as Affected by Soil Texture and Residual Fertilization in Tropical Soils
(Taylor & Francis Inc, 2010-01-01)
Potassium (K) leaching is affected by soil texture and available K, among other factors. In this experiment, effects of soil texture and K availability on K distribution were studied in the presence of roots, with no excess ...
Pay it forward: refuse dump from leaf-cutting ants promotes caterpillar digestive performance by increasing plant nitrogen content
(Wiley Blackwell Publishing, Inc, 2019-02-09)
1. The activity of soil-disturbing animals that increase soil nutrients can affect the carbon : nitrogen (C : N) ratio of plants, which, in turn, may determine the transfer of energy and nutrients through higher trophic ...

Annual and monthly quantities of nutrients wich returned to the soil through litter fall in Pinus elliottii Engelm. var. elliottii stand were estimated durint a two years period, in Experimental Station of Mogi-Guacu, SP. ...
Availability of nutrients, productive properties, and quality of sunflower ( L.) seeds in acid soils amended with different molar ratios between Ca and Mg
Liming is indispensable in acid soils for amending acidity; however, the technique may alter the cation balance in soil and, consequently, may limit the availability and uptake of nutrients. We aimed to evaluate different ...
Fitomassa e acumulo de macronutrientes em cana-de-açúcar sob compactação e umidade do solo
The experiment was conducted in PVC tubes, in a greenhouse, using a randomized block design with four replications, in a factorial arrangement (4x3x2) equivalent to four varieties, three levels of soil compaction in the ...
