Soil compaction can reduce the growth of crops, causing production losses even in soil conservation systems. In areas where controlled traffic is used, the wheeled rows are prone to show limiting conditions for corn growth and production. Determination of soil critical values limiting plant growth and corn grain productivity in areas with controlled traffic would be a valuable tool to adopt controlled traffic. Aiming the assessing of critical values to soil compaction an experiment was designed on a Rhodic Paleudult as random blocks in factorial scheme 2x4x5 (tillage x wheeling x soil layers), with three replications. Maize was sown with direct drilling (zero tillage) and reduced tillage (chiseling) system. A tractor with 3.8 Mg was used to compact soil in both systems (0, 1, 3 and 6 wheeling) prior to sowing. The soil density, macro porosity and field capacity were determined in undisturbed soil samples taken at 0-5; 5-10; 10-15; 15-20 and 20-25 cm dept layers. Soil penetration resistance (PR) was evaluated in the field as well. Regardless of tillage system, traffic increased agricultural soil density values even to the depth of 20 cm. The highest value of PR (1600 kPa) and soil density (1.67 Mg m-3) were not limiting to maize growth and the productivity of corn grains increased on wheeled soil. Water content of the soil after wheeling, at field capacity, was increased by up to 0.1 m3 m-3 and the macro porosity was reduced in 10%. The grain production of corn was higher in wheeled soil. The values of soil density and PR were not limiting to root growth. Wheeling the soil even up to six times with tractor, did not limit maize growth, and showed increases in grain productivity.

Este trabalho teve como objetivo avaliar o efeito do fertilizante organomineral enriquecido com ácido cítrico na acumulação de matéria seca e fósforo (P) em plantas de milho cultivadas em casa de vegetação. Utilizou-se o delineamento em blocos ao acaso, com fatorial 6x3, combinando seis fontes de P (superfosfato triplo, fosfato natural reativo de Bayóvar, superfosfato + cama de aviário, fosfato Bayóvar + cama de aviário, superfosfato + cama de aviário + ácido cítrico, fosfato Bayóvar + cama de aviário + ácido cítrico), três doses de P aplicado (40, 80 e 120 kg ha-1 de P2O5), com quatro repetições. Os fertilizantes organominerais produzidos com superfosfato triplo propiciaram maior acumulação de matéria seca e P na parte aérea de milho, do que os fertilizantes organominerais com fosfato Bayóvar. As plantas que receberam os fertilizantes organominerais com superfosfato apresentaram maior acumulação de biomassa e P na parte aérea que as plantas que receberam apenas superfosfato, sem efeito do ácido cítrico. O ácido cítrico adicionado ao fertilizante organomineral produzido com fosfato de Bayóvar aumentou a acumulação de P na raiz. Conclui-se que a incorporação de matéria orgânica ao fosfato solúvel aumenta o crescimento do milho e que a adição de ácido cítrico aos fertilizantes organominerais produzidos com fosfato natural aumenta a matéria seca de raiz. |
