Inhaltsangabe

Excerpt from Soil Management for Intensive Vegetable Production on Sandy Connecticut Valley Land<br/><br/>Since the 20-ton manure treatment more than maintained the original organic content of the soil, it is reasonable to suppose that a lighter applica tion would have prevented any decline. The data are not sufficient to reveal the minimum rate of manuring needed for exact soil organic matter stabilization. However, under the program of intensive cropping without green manure or cover crop used in these trials, it seems likely that 16 tons of manure per acre per year would prevent any decline in soil organic matter. It should be understood that this is based on' results on a light sandy soil containing approximately percent of organic matter. A summary of relative yields in manure and fertilizer comparisons for all crops grown for more than four seasons of these trials is shown in Table 5.
