Title
Results from Subsoiling and Deep Fertilization of Corn for 2 Years
W. K. Robertson; J. G. A. Fiskell; C. E. Hutton; et al. Soil Science Society of America Journal 1957. doi:10.2136/sssaj1957.03615995002100030023x
Other claims from this paper (9)
- Intervention effect On soils with organic hardpans, subsoiling alone increased corn yields.
- Intervention effect On soils with organic hardpans, fertilizer, lime and/or minor elements placed in the subsoil increased corn yields.
- Association Responses to fertilizer were related to the chemical composition of the soil profile and to rainfall distribution.
- Association Corn responses were better when moisture stress periods occurred during the first part of the season.
- Intervention effect With short drought periods, subsoiling and deep placed fertilizer improved corn yields above the check.
- Association With a 25-day drought, the advantage of a deeper root system and larger corn plant was lost.
- Intervention effect On Klej fine sand, surface fertilizer gave corn results as good as deep placement.
- Intervention effect On Klej fine sand, subsoiling alone gave no benefit to corn.
- Recommendation The authors suggest that corn may need subsoiling every year, although additional subsoil fertilizer may not be needed.
