Average kainit will contain from 30 to 40 per cent of this material. Ordinary- waste meat salt used at the rate of 400 to 600 pounds per acre has been found in experimental work to greatly reduce this trouble with cotton. It is more than probable that for such crops as tobacco, potatoes, and legumes, applications of potash, when prices are normal, will in many cases, at least, prove to be profitable. Especially is this so when the soils are low in organic matter, notwithstanding fairly good crops might be grown without such applications. In experiments on the Alamance Silt Loam type of soil near Monroe in Union County, the soil being fairly low in organic matter, it has been found that the use of potash when obtainable at normal prices has increased the yields of an oat- and-vetch mixture for hay, and of seed cotton in sufficient amounts to justify its use. It is believed that with the organic matter supply materially increased in this soil, as well as other types of soil occurring in the county, the necessity for applications of potash may not be in many cases necessary in order to secure good Fio. 11.—This grass mixture will do well on the soils of the county, if properly put in and manured With all the main types of soil occurring in the county when they arc low in organic matter, nitrogen has been shown to be of chief im- portance. Upon increasing the amount of organic matter in the soil the necessity for applications of materials carrying nitrogen in available form is greatly reduced. All the soils of the county, types of which have been examined chemically, are low in nitrogen and organic matter, and.
