Adubação nitrogenada na cultura do milho com ureia revestida por diferentes fontes de polímeros
(Univ Estadual Londrina, 2014-01-01)
In view of theoretic increase in efficiency of nitrogen fertilizers for controlled release, this study aimed to evaluate the effect of nitrogen, using conventional urea and ureas coated by different polymers, in the leaf ...
Growth of Hymenaea stigonocarpa as a function of the addition of residues in degraded soil
(Univ Federal Campina Grande, 2016-03-01)
In areas where soil surface horizons were removed, the main edaphic problems are reduced amounts of organic matter and nutrients. Revegetation, especially with native species, has been indicated to recover these areas. ...
COMPARATIVE ASSESSMENT OF THE NUTRITIONAL STATUS FOR BARU (Dipterix alata) SEEDLINGS
(Centro Pesquisas Florestais, Ufsm, 2016-01-01)
To a successful revegetation process, besides improving the edaphic area conditions, seedlings must have good quality, which can be assessed by nutritional status. This research evaluated the foliar contents of N, P, K, ...
Avaliação comparativa do estado nutricional de mudas de baru (Dipteryx alata)
(2016-01-01)
To a successful revegetation process, besides improving the edaphic area conditions, seedlings must have good quality, which can be assessed by nutritional status. This research evaluated the foliar contents of N, P, K, ...
Soil fauna: Bioindicator of soil recovery in Brazilian savannah
(2017-01-01)
This work aimed to evaluate the employment of the soil arthropod community as a bioindicator of land reclamation on a loan area in Mabea fistulifera Mart. plantation under different types of fertilization, in central-western ...
Empirical stomatal conductance models reveal that the isohydric behavior of an Acacia caven Mediterranean Savannah scales from leaf to ecosystem
(Elsevier, 2015)
Canopy conductance (g(c)) is the main controller of plant-atmospheric interaction and a key element in understanding how plants cope with drought. Empirical g(c) models provide a good inference as to how environmental ...
Soybean grown after green manures under no-tillage and conventional management systems in savannah soil
(Empresa Brasil Pesq Agropec, 2004-11-01)
The green manures aim to preserve the environment quality without discarding the largest yield of economic crops. The objective of this work was to evaluate the performance of soybean grown after green manures under ...
Liming effects on growth of native woody species from brazilian savannah.
(Pesquisa Agropecuaria Brasileira, Brasilia, v.34, n 5, p.829-37, maio 1999., 2011)
Assessing soil microbial biodiversity as affected by grazing and woody vegetation cover in a temperate savannah
(Wiley, 2021-04-07)
Although it is well established that land use and management affects soil microbial biodiversity, with consequences for soil-mediated ecosystem services, knowledge on human-induced variability in soil bacterial and fungal ...
