Effect of irrigation and fertilization on some chemical characteristics of a Vertisol

Effect of irrigation and fertilization on some chemical characteristics of a Vertisol

The effect of irrigation and fertilizer applied annually for 17 years was evaluated for some chemical characteristics of a Vertisol cultivated with grapevine. The water was applied through a border irrigation system. The fertilizers were broadcasted between the rows of vines and incorporated into the soil up to a depth of 5cm. The soil samples were collected from 18 points of the cultivated area and from seven points of the virgin soil, around the grapevine orchard, at depths of 0-15 cm, 15-30 cm, 30-60 cm, 60-90 cm e 90-120 cm. The analytical results showed that practically there were no perceptible variations in the amount of exchangeable Ca2+, Mg2+ and Na+, organic matter, N-NH+4, and Zn in relation to virgin soil. Concerning the other parameters it was observed that in the upper layers there was a decrease of the pH and an increase of the electrical conductivity (EC) and of exchangeable K+, P, total N, N-NO-3, Cu, Mn and Fe. These differences, however, decreased with the depth except for Fe. Higher concentration of Cu and Mn should have been consequence of the annual application of fungicide and/or solubilization of compounds containing these elements. The results obtained indicate that the changes observed in some parameters, as a result of the application of irrigation water and fertilizers to the soil, should not interfere with the yield capacity of the soil.

Em um Vertissolo, cultivado com videira, avaliou-se o efeito da irrigação e da adubação NPK aplicadas anualmente, durante 17 anos, sobre algumas características químicas do solo. O sistema de irrigação foi em bacia de infiltração, onde também foram aplicados os fertilizantes e incorporados ao solo até a profundidade de 5 cm. A amostragem do solo foi feita em 18 pontos da área cultivada e em sete pontos da área de solo virgem, em torno do parreiral, às profundidades de 0-15 cm, 1 5-30 cm, 30-60 cm, 60-90 cm e 90-120 cm. Os resultados analíticos mostraram que praticamente não ocorreram variações perceptíveis nos teores de Ca2+, Mg2+ e Na+ trocáveis, matéria orgânica, N-HN+4 e Zn, em relação ao solo virgem, em resposta aos tratamentos. Quanto aos outros parâmetros, constatou-se que nas camadas superiores houve diminuição do pH e aumento da condutividade elétrica (CEe) e dos teores de K+ trocável, P, N total, N-NO-3, Cu, Mn e Fe. Estas diferenças, com exceção do Fe, diminuíram com a profundidade. Teores mais elevados de Cu e Mn devem ter sido consequência da aplicação anual de fungicidas e da solubilização de compostos contendo estes elementos. Os resultados obtidos indicaram que as variações ocorridas em alguns parâmetros, decorrentes da irrigação e aplicação de fertilizantes, principalmente aquelas relacionadas com o aumento da salinidade, não devem comprometer a capacidade produtiva do solo.
