Book excerpt: Excerpt from Deep-Tillage Investigations on Alluvial Soil in the Sugarcane Area of Louisiana Although no significant crop response was obtained in the tests in 1957-59 and 1961-62 on silt loam alluvium, there was a significant soil physical response. The explanation for the lack of crop response is not known. One influential factor may have been the relatively high yield of the conventional plots. The average crop response of tests in 1955-59 and 1961-62 on silty clay loam alluvium for subsoiling 14 and 18 inches deep was standard tons per acre; plowing 14 inches, and plowing 18 inches, The crop response obtained by deep plowing 14 inches deep on 16 replications was significant at the 5-percent level, and that by deep plowing 18 inches deep on 26 replications was significant at the l-percent level. The tillage treatments caused little change in the soil physical characteristics. No crop responses were obtained from deep tillage tests in 1955-56 on clay alluvium or in tests in 1957-58 on loess silt loam uplands, although the soil properties of the silt loam uplands did change. Limited soil moisture studies indicate that during periods of sparse rainfall the deep-tilled plots contained more moisture at the 0 to 12-inch depth than conventional plots. These plots also showed a greater moisture extraction at the 24 to 36-inch depth, which indicates a deeper rooted crop. In a sugarcane x tillage interaction study, the variety C. P. 44-101 produced a significantly higher yield of standard tons per acre from the'14-inch deep-plowed treatment, as com pared with the 14 or 18-inch subsoiled treatment. The reverse was true with the variety C. P. 36-105, which produced more standard tons per acre from the subsoiled treatment. The reverse was true with the variety C. P. 36-105, which produced more standard tons per acre from the subsoiled treatment. In other studies, the variety c.p. 44-101 showed the same pattern of tillage treatment response.
