1292. Chaudhary, T.H.. 1976. The effect of nitrogen source and 2-chloro-6-(trichloromethyl) pyridine (N-Serve) on the nitrogen and sulfur nutrition of wheat.. Ph.D. Thesis, Dept. of Agronomy and Soils, Washington State Univ., Pullman, WA.
The effects of urea applications with and without the product N-serve were examined. N-serve considerably reduced the loss of NH4+-N to organic transformations, and resulted in much higher amounts that were available to plants. Some problem of N toxicity resulted, but this was presumed to also be related to a lack of sulfur. T: Many. e.g.:Changes in the organic N content of the soil and N uptake by plants. Amounts of NH4+-N and NO3--N in the soil in April and August. Dry-matter yields and percentage uptake of N and S.
