Phosphorus and potassium budget in the soil-plant system in crop rotations under no-till
(2013-01-01)
Soil management and crop rotations can affect P and K budget in soil, decreasing losses, and increasing fertilizer use efficiency. The P and K budget in the soil-plant system at depths up to 60. cm was studied for different ...
The primary sources of carbon loss during the crop-establishment period in a subtropical Oxisol under contrasting tillage systems
(Elsevier B.V., 2011-12-01)
The physical protection of mineralizable carbon (C) in aggregates has been identified as the primary mechanism of soil C stabilization. Therefore, it is possible to hypothesize that the disruption of aggregate by soil ...

In search of economically significant food losses: Evidence from Tunisia
(ELSEVIER SCI LTD, 2021)
Large estimates of food losses among farms and intermediaries publicized recently by several international organizations invite the question: Why do economic decision makers live with such losses? The intuitive, economic ...
Exoferality in sunflower (Helianthus annuus L.): A case study of intraspecific/interbiotype interference promoted by human activity
(Elsevier Science, 2013-05)
Helianthus annuus subsp. annuus, a biotype of the same species of the domesticated sunflower H. annuus var. macrocarpus, is an emergent noxious weed in several regions ofthe world. The frequent hybridization that occurs ...

Multi-level analysis of bird abundance and damage to crop fields
(Elsevier, 2014-12)
Bird damage to agricultural crops is an important cause of economic loss for farmers worldwide. Predictive habitat models relating bird abundance and damage to characteristics of the agricultural environment at multiple ...
Praedial larceny : the Domino Effect
(2016)
It is not uncommon for a complete truckload of goats or an entire field of pineapples to be stolen, or a pot of fish at sea to be harvested by praedial larcenists. Available statistics show that commercial crop farmers ...
Ammonia losses by volatilization in response to nitrogen fertilization of bean common crop
(Univ Estadual Mato Grosso Sul, 2016-01-01)
Nitrogen (N) is one of the nutrients that most limits the growth and development of plants, mainly because of its wide dynamics in the soil-plant-atmosphere system. Among the various processes that this element is subject, ...
