Abstract:
Cotton is a major irrigated summer field crop in Israel, and is commonly grown in the same field for 3-5 years in succession. There is only a narrow time window between harvest and early rains for pest control by means of clearing the land surface of residues, and to perform preparatory tillage. The time available may be insufficient to achieve this with the conventional deep plowing tillage system, and some operations may have to be carried out on moist soil between rainfall events. In response to indications of decreasing yield due to compaction, various limited-tillage systems in permanent traffic lanes have been developed, culminating in a machine that performs all residue-disposal and tillage operations in a single pass through the field. A comparison of several limited-traffic and conventional practices was carried out for 2 years on a loessial silt loam (Calcic Haploxeralf). It was found that both soil condition and yield were worst in the two treatments commonly used by farmers: deep plowing and deep incorporation of residues with the combination machine. Tillage effects were dominant, masking any effect of residue amount and disposal method. Large differences were found between the zones of the permanent wheel track treatments, as were cyclic changes in soil condition reflecting the seasonal sequence of tillage operations. Some cumulative compaction occurred, due mainly to a gradual widening of the wheel tracks rather than to repeated passes in the original rut. The findings of this work show that the optimal choice is to replace the previously preferred field practices by shallow slot-mulching with simultaneous subsoiling by the combination machine, which meets the sanitation requirements, maintains satisfactory yields and saves energy and labor. © 1994 Elsevier Science B.V.

The effect of various residue mulch-tillage combinations on soil physical conditions and performance of irrigated cotton
Cotton is a major irrigated summer field crop in Israel, and is commonly grown in the same field for 3-5 years in succession. There is only a narrow time window between harvest and early rains for pest control by means of clearing the land surface of residues, and to perform preparatory tillage. The time available may be insufficient to achieve this with the conventional deep plowing tillage system, and some operations may have to be carried out on moist soil between rainfall events. In response to indications of decreasing yield due to compaction, various limited-tillage systems in permanent traffic lanes have been developed, culminating in a machine that performs all residue-disposal and tillage operations in a single pass through the field. A comparison of several limited-traffic and conventional practices was carried out for 2 years on a loessial silt loam (Calcic Haploxeralf). It was found that both soil condition and yield were worst in the two treatments commonly used by farmers: deep plowing and deep incorporation of residues with the combination machine. Tillage effects were dominant, masking any effect of residue amount and disposal method. Large differences were found between the zones of the permanent wheel track treatments, as were cyclic changes in soil condition reflecting the seasonal sequence of tillage operations. Some cumulative compaction occurred, due mainly to a gradual widening of the wheel tracks rather than to repeated passes in the original rut.
