Editorial Note on Input and Production of Nutrients in an Agroforestry Environment

Abstract

Alternatives to conventional agricultural farming methods, such as agroforestry systems, which merge production and environmental protection, are currently being studied. The purpose of this analysis was to measure the contribution of trees to the input and production of nutrients in crops grown in the agrosilvopastoral system in Sobral municipality, Ceara Province, Brazil. In the rainy and dry seasons, nutrient concentrations were quantified in Cordia oncocalyx Allemao (called pau-branco) trees in shade and sun leaves and at harvest time in maize leaves. Concentrations of nutrients in various soil layers (0-10, 10-20 and 20-40cm) were also quantified from the trunk of C at 0.4 and 4.0 m. Oncocalyx trees with trees. Also measured was the contribution of the trees to the nutrient input to the scheme and the nutrient production due to the elimination of maize plants. The land under the canopy of C. The maximum concentrations of total N, K, P, Fe, Cu, Zn and Mn were seen by oncocalyx. In the concentrations of maize leaf nutrients, however, few variations were noted as a result of the distance from the trunk. The trees will produce up to 35 kg ha-1 Ca, 19 kg ha-1 N and 15 kg ha-1 K, while roughly 2.3 kg N, 5.6 kg K and 0.2 kg Ca leave the maize plant shoot removal method. The conservation of trees in processing systems thus contributes greatly to the replenishment of the nutrients depleted from seed harvesting.
