Many Hawaiian agricultural soils are acidic with low-nutrient retention;therefore,organic soil amendments are often used to improve soil properties and increase yields.Amendments can be incorporated for annual crops,b...
Among Brazilian soils orders, there are some of it classified as acid soils, which need correction to guarantee crop productivity. Currently, limestone is the most used soil corrective and wood ash has been a sustaina...
The growing concern with the quality of life and the environment, due to the degradation of natural resources and their contamination, mainly with agrochemicals, led to the emergence of a sustainable or alternative ag...

Silicon (Si) has been supplied to plants via application of calcium silicate to soil; however, high doses of calcium silicate are required because of its low solubility. Nanoparticles can reduce Si doses and be appl...
Cowpea, string Bean, or Macassar bean [Vigna unguiculata (L.) Walp] presents a short life cycle, low water requirement, develops in soils of low fertility, and has the ability to fix nitrogen from the air. In the Cerr...
The safflower (Carthamus tinctorius L.), in particular, has been soaring in significance as an alternative for oil and biodiesel production. In this context, the goal of this study was to assess the influence exerted ...
The use of cover plants promotes the recycling of nutrients and the increase in organic mass, and minimizes the effects of erosion. The objective was to evaluate the effect of bulk density in the development of jack b...
A major nutritional problem to crops grown in highly weathered Brazilian soils is phosphorus (P) deficiencies linked to their low availability and the capacity of the soils to fix P in insoluble forms. Our studies exa...
O uso do sistema plantio direto (SPD) com plantas de cobertura melhora a agregação do solo. O objetivo desse trabalho foi avaliar a estabilidade dos agregados em água e a distribuição do carbo...
