Potassium leaching from millet straw as affected by rainfall and potassium rates
(Communications in Soil Science and Plant Analysis, 2005-05-27) [Artigo]
Pearl millet (Penisetum glaucum) is an interesting species to be used as cover crop in tropical areas, showing a high ability in potassium uptake. Potassium (K) is not linked to organic compounds in the plant, and can ...
Lixiviação de potássio da palha de plantas de cobertura em diferentes estádios de senescência após a dessecação química
(Revista Brasileira de Ciência do Solo, 2005-02-01) [Artigo]
O manejo químico de espécies de cobertura do solo é prática usual em sistemas de semeadura direta, e a mineralização de nutrientes dos restos vegetais deixados na superfície do solo pode ser intensificada pela ação da água ...
Kinetics of zinc uptake and anatomy of roots and leaves of coffee trees as affected by zinc nutrition
(Journal of Plant Nutrition, 2005-01-01) [Artigo]
Zinc (Zn) uptake kinetics and root and leaf anatomy were studied in coffee trees grown in nutrient solutions with or without Zn. Leaves and roots were sampled and cuts were made in the medium part of the leaves and in root ...
Leaching of nitrate and ammonium from cover crop straws as affected by rainfall
(Communications in Soil Science and Plant Analysis, 2005-01-01) [Artigo]
Nitrogen (N) mineralization dynamics in no-till systems is affected, among other factors, by N amount and quality in the mulch and by climatic conditions. Leaching of NO3-N and NH4-N from six plant species used as soil ...
