Composted cow manure sample was collected from filed of college of Agriculture, University of Basrah. Its properties were identified. Humic acid was extracted from cow manure and diagnosed according to elemental analysis (CHN), spectral study (E4/E6), infra-red spectrum (IR), in addition to chemical composition of functional groups. Two types of humic acid were prepared, one of them humic acid with fermented plant residue (HA1-N) and other humic acid with zeolite (HA2-N). A laboratory experiment was carried out to study the amount of ammonia volatile from two prepared chelate fertilizers (HA1-N and HA2-N) and urea fertilizer by incubation two types of soils (sandy soil and clay loam soil) at 35°C with four rates of nitrogen (0, 125, 250 and 500 mg N kg-1 soil) and with five incubation time (3, 6, 12, 24 and 48 days). The study found that increasing rate of nitrogen and incubation time increased ammonia volatilization, and the highest value was at the rate 500 mg N kg-1 soil and at 48 days of incubation to reach a 21.427 and 9.736 mg N-NH3 Kg-1 soil for sandy soil and clay loam soil, respectively. Application of two prepared chelate fertilizers (HA1-N and HA2-N) at rate 500 mg N Kg -1 reduced ammonia volatilization to 99.30 % and 98.62 % for sandy soil and 98.96 % and 97.77 % for clay loam soil comparing with urea fertilizer . Fertilizers were took the following order in reducing ammonia volatilization : HA1-N > HA2-N > Urea.

Beneficial microorganisms play a key role in the availability of ions minerals in the soil and use Randomized Complete Block Desing ( R.C.B.D ). The objective of this paper to the study effect of the of biofertilizer and miniral treatments on availability of NPK for crop corn zea mays L.Two types of biofertilizer are Bacterial Bacillus subtilis and Fungal Trichoderma harianum. Three levels of potassium fertilizer are (2.9533, 0.4000 and 2.9533). A field experiment in fall season of 2018 Has been conducted in silty clay loam soil. The experimental Results indicated that Bacillus and Trichoderma inoculation separately or together Have made a significant effect to increase in the availability of N P K in the soil compare to other treatments. The grain yield is where (2.9533, 0.4000 and 2.9533) of bacterial and fungal bio-fertilizer and potassium fertilizers respectively as compared to the control.

Potato Yields

The experiment testing N residues (made on a clay-loam soil) clearly showed that N applied for potatoes benefited the following wheat crop, but that N applied for wheat benefited the following potato crop little. There were no worth-while 1. An experiment on a clay-loam soil measured responses to three amounts of nitrogen on alternate crops of wheat and potatoes; these dressings were tested in all combinations with three rates of N applied 1 and 2 years previously. Nitrogen applied for potatoes consistently increased yields of following wheat. The residue from applying 1·5 cwt. N/acre for potatoes was equivalent to topdressing the wheat with 0·55 cwt. N/acre; the value of the residue was decreased by applying N to the wheat. Potato yields were increased little by applying N to the preceding wheat crop and the residues were of little significance when compared with the responses to new N. There was no gain from N applied 2 years previously for either crop.

McCall, Maple Presto, Maple Amber and OT80-3 soybean (Glycine max (L.) Merr.) cultivars were evaluated under field conditions for their response to metribuzin. Maple Amber was found to be less tolerant than the other cultivars. In controlled environment chamber studies, injury to this cultivar was more severe on a sandy loam soil than on a clay loam soil. Fall applications of metribuzin, alone or tank-mixed with trifluralin, were tolerant to Maple Amber soybeans and such applications may offer a practical alternative to spring treatments for broad spectrum weed control in the less tolerant soybean cultivars grown in Manitoba.Key words: Metribuzin, trifluralin, preplant incorporation, fall treatments, soybean cultivars
