Tea Manuring

Abstract

One of the first matters to which I turned my attention ten years ago was the compilation of a recipe book of manures, to include every formula I could lay my hands on. In the near future, I should be called on to advise on manuring and to work out a scheme for experimentation, and I was seeking a datum line from which to work. I soon found that there appeared to be few, if any. guiding principles, on the quantitative side, that welded together into an intelligent whole the immense variety of prescriptions in vogue. It would hardly be an exaggeration to say that any combination of amounts from 10 to 40 lb. per acre for all the three standard nutrients. if picked at random out of a hat, would have been found to correspond closely to examples in actual use.
