The following are the resultsFrom 3, yards manured with No. When making these assertions I ought to state that my experience of wheat-growing does not extend beyond the counties of York and Lancaster, but from what I can learn of the agriculture of more southerly districts, I fancy these opinions of mine will be found correct even there. As I still continue the experiment, I shall be in a position to continue the account up to the present time as I am now threshing out the last year's cropand will send it to you if you think it worthy of insertion in the "Agricultural Gazette. In the use of silicates of soda and potash, one precaution is very necessary, namely, that you really have a soluble silicate, not a mere mechanical mixture of ground flint and alkali.

Progress in the long-term trials methodology and the mathematical methods of experimental data processing Agroconsult, Moscow. The crop promised to be a very good one, but it was much plundered by the birds, and as the summer was wet, it suffered also much from rust. My experiments so far are opposed to this theory, but it is not very safe or philosophical to draw conclusions from one or two experiments only.

Environmental myopia: a diagnosis and a remedy.

Rescue grass thrives, and a mixture. I was led into these experiments by reading Liebig's book on the "Chemistry of Agriculture;" for, assuming his theory to be true, it appeared to me to be quite possible to grow wheat on the same land year after year; as, according to that theory, the carbon, oxygen, and hydrogen, which constitute the great bulk of all cereal crops both grain and straware supplied in abundance from the soil and atmosphere or perhaps, to speak more correctly, from the latterand we have only to supply those inorganic substances, which, however numerous, form but a small part of the whole weight of the crop. I had a striking proof this season of the much lower temperature required by oats than wheat, when strongly stimulated by manuring. I shall be glad to hear the result of your electrical experiment--at present I am rather sceptical on the subject. Identification of critical soil phosphate P levels for cereal and oilseed rape crops on a range of soil types Final Project Summary. It was not fit to cut for three weeks after the experimental field, although it was an early white wheat, and the result was a miserable crop--far worse than the experimental field.

Again, the silicate of soda may be properly made, in the first instance, but in a long exposure to the atmosphere, the soda attracts carbonic acid, and is liberated from the silex, and this has disappointed my expectation more than once.

Again, admitting that it is not practicable to grow wheat on the same land year after year on a large scale, yet if we can double the crop in those years in which we do grow it, by the application of chemical manures and the same manures are applicable to all cereal cropswill not that be a conclusion worth arriving at?

Fully sensible of my inability to do justice to this important subject, I yet hope if you do me the honour to publish my letter that my remarks may induce scientific men to consider it; for it appears unaccountable to me that hitherto they seem to have thought it unworthy of their attention.

Des experimentations de longue duree sur la recherche en environnement. Journal Of Archaeological Science. In the first year's experiment the produce from guano alone was 27 bushels per acre, and both straw and wheat were very indifferent in quality.

With respect to the lime used, it may be as well to state that the field had not been limed for many years, and although in a limestone district, showed a deficiency of lime on analysis. My idea is that it does both, and that carbon in the soil does good if it offers an abundant supply of carbonic acid to the plant when it is in a condition to appropriate it.

I also saw Liebig's letters explaining the action of quicklime in liberating potash from the clay; and then I considered it very important to ascertain the proper quantity to be applied.
