“…The greatest removal of N and K from the field by the root system was recorded in the growth stages, while less removal of Ca was observed. However, it´s not yet clear how to establish the ideal relationship between the nutrients N, K and Ca in the soil to favor the absorption by the plants, because the amount of ions that reach the surface of the root of the plant depends on different factors, including the concentration of nutrients in the soil solution, the volume of the soil that is filled with water, size of the root system, root length, root diameter, among others (Rashmi et al, 2017).…”

Increasing cassava yield in response to growing consumer market demand requires good management practices to avoid degradation caused by soil nutrient depletion. The objective of this work was to evaluate components of macronutrient production and extraction of cassava in consortium with the legume Crotalaria juncea. A statistical design was used in randomized blocks, with four replications, in plots subdivided in time. In the plots were the treatments presence and absence of cassava consortium with C. juncea, the subplots were formed by 11 evaluation periods every 30 days for the production components and 6 evaluation periods every 60 days for the extraction of nutrients. The following were evaluated: production components (partitioned yields and total wet and dry mass - t ha-1) and extraction of macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur - kg ha-1). The water balance of the crop was determined on a monthly scale. The annual evapotranspiration of cassava was 1,273 mm in the 12-month cycle. The agricultural productivity of roots, stakes, stem, leaves, shoot and total biomass of cassava was 18.4, 1.8, 7.2, 2.7, 9.9 and 30.1 t ha-1, respectively. The dry mass yield of roots, stakes, stem, leaves, shoot and total was 5.1, 0.8, 2.1, 0.9, 3.0 and 8.9 t ha-1, respectively. There was a higher extraction of nitrogen by cassava, 119 kg ha-1, followed by calcium, potassium, magnesium, phosphorus and sulfur. The cassava consortium with C. juncea did not interfere in the variables studied.

Background: Phosphorus (P) is among the essential elements for plant growth and one of the main elements of fertilizers. Decreased availability of P may limit agricultural production in the coming years. The magnitude of soil aggregation influences phosphorus access to mineral surfaces. Aim:The present study aims to determine phosphorus adsorption processes affected by soil aggregation under different land-use systems. Methods:The distribution of soil aggregates was determined in representative soil samples in the district Kupwara of Kashmir Valley in India. To predict the phosphorus fertilizer requirement of a particular soil, we used the Freundlich adsorption equation and Langmuir equation and drew a clear comparison between these two models.Results and discussion: Maximum phosphorus (P) adsorption was recorded at the smallest aggregate size, 0.5-0.1 mm. However, soil aggregates >2.0 mm (the largest category) adsorbed the least amount of P. Our results revealed that increasing the addition of P to the soil decreased the percentage of adsorbed P regardless of aggregate size. The maximum P adsorption of different size aggregates varied between 1869-1924, 1872-1900, 1718-1739, and 1800-1890 mg P kg -1 in irrigated agriculture, forest, orchard and rainfed agriculture soils, respectively. The variation in P adsorption parameters across the different land uses was attributed to their mean weight diameter difference. The maximum bonding energy in the forest resulted in higher P adsorption. Langmuir and Freundlich's adsorption equations were fitted to each soil aggregate size and land-use system.
