Although the quantity of organic matter compared to the total weight of most mineral soil is relatively small, it can dramatically influence the soil's physical and chemical properties.
With wheat the increase in growth can be attributed solely to the extra mineral nitrogen released by irradiated soil. However, ryegrass grew a little better than would have been expected if the only effect of irradiation was to increase the release of soil by: Effect of different levels of fertilizer on growth, yield and quality of late sown wheat.

the effect of various concentrations of mineral fertilizers on germination and growth of ryeAuthor: Azra Hadzic. Cumulative nitrogen uptake in wheat follows a sigmoid (or “S” shaped) curve giving rise to the three phases (Figure 1). Nitrogen uptake is slow during the early growth phase from emergence into tillering (Phase 1).
Rapid accumulation of nitrogen occurs in Phase II, which corresponds to the stem elongation phase from jointing to heading. The fertilizer effect of ryegrass plant material in spring barley was studied during two suceessive growing seasons.
The aim of the study was to investigate whether the level of mineral fertilizer could be reduced after incorporation of a catch crop. To simulate standard agronomic practice, referenc plots and amended plots were fertilized with mineral N fertilizer Cited by: The current experiments were carried out to evaluate the effect of different organic (biochar and FYM) and inorganic amendments nitrogen as urea) on the growth and phenology of wheat.

Effects of increasing rates of nitrogen (N) and sulphur (S) fertilizers on the yield, digestibility, and composition of N, S, and amino acid of perennial ryegrass (Lolium perenne L.) was studied in a pot experiment using an under-developed S-responsive (Harvey) and a developed non-S responsive (Gorge) soil.

Zeeb Rd. Ann Arbor, MI The yield of biomass of cover crops was obtained prior to ploughing-in in the spring. The above ground biomass of cover crops was obtained by cutting the crop to a stubble height of 5 cm from the ten quadrates (50 cm × 50 cm) of each plot, and then weighing by: The residual effect of 2-year-old swards of clover-ryegrass mixture and ryegrass in monoculture on yield and N uptake in a subsequent winter wheat crop was investigated by use of the 15 N dilution method and by mathematical modelling.

Three field experiments in Eastern England, in which 15 N-labelled fertilizer had been applied to winter wheat, were used to measure the persistence of the labelled N remaining in soil and stubble at harvest and the availability of this N to up to four subsequent wheat crops.
A portion of the labelled fertilizer N quickly became stabilized in the soil, with only small and ever Cited by: treatments drilled into wheat stubble each year significantly low - ered the NO 3 –N levels in the soil the following spring without affecting soybean crop yields. Yet no additional effects related to cover cropping were evident in soils or crops after one CC growing season.
Also for Illinois and under no-till, Villamil et al.

For European crops little information from field experimentation with elevated CO 2 levels ([eCO 2]) exists, which may be used for model validation six years an arable crop rotation with winter barley, ryegrass, sugar Cited by: Some organic farms are demonstrating large N carryover and may not need any spring nitrogen.
Unfortunately, no soil test exists that will predict how much nitrogen carryover to expect. In early spring, it is possible to tissue test a wheat crop and determine how much additional nitrogen, if any, is needed to produce an optimal yield. Wheat crop suppresses the growth of annual ryegrass (24) wheat extracts inhibited the seed germination and seedling growth of Amaranthus retroflexus, Stellaria media and Digitaria ciliaris (11).
Allelochemicals such as phenolic compounds are often associated with allelopathic effects of wheat. The guidelines for Maximum Economic Yield - Spring Wheat Production suggests split applications of nitrogen as follows: 40% pre-plant, 10% in starter, 25% at tillering (Zadoks Growth Stage ) and 25% at stem elongation (Zadoks Growth stage ).
An additional nitrogen application of about kg/ha ( lb/ac) swollen boot (Zadoks. Abstract. The organic matter content of agricultural soils is highly correlated with their potential productivity, tilth, and fertility. Although the amount of soil organic matter (SOM) in most semiarid dryland soils is relatively low, ranging from to 3% and typically less than 1%, its influence on soil properties is of major by: To maintain organic matter in low residue producing crop systems like vegetables, sow Sorghum, Sorghum-Sudan hybrids, Sudan grass, or corn to produce a high level of biomass.

Hence, there are cumulative effects of cropping systems with abundant organic inputs on soil total N contents that could influence levels of plant-available N and thus yields of cereal crops. In contrast, residual ef-fects of N added with mineral fertilizers are negligible (Petersen et al., ).

Three successive crops of winter wheat were grown on a sandy loam to test the residual effect of long-term annual incorporation of spring barley straw at rates of 0, 4, 8 and 12 t ha −1, and ryegrass catch crops with or without additions of pig receiving 4, 8 and 12 t ha −1 of straw annually for 18 years contai 21 and 30% more carbon (C).
Soil organic carbon (SOC) has a vital role to enhance agricultural productivity and for mitigation of climate change. To quantify SOC effects on productivity, process models serve as a robust tool to keep track of multiple plant and soil factors and their interactions affecting SOC dynamics.
We used soil-plant-atmospheric model viz. DAISY, to assess effects of SOC on nitrogen (N) Cited by: Common chickweed, an annual or overwintering native plant, is one of the commonest weeds of cultivated land in the UK.
It also occurs on roadsides, shingle riverbanks, coastal cliffs and in gardens. It is widely distributed over all soil types but is more abundant on lighter soils. During the growing season, total season yields were more t lb/acre for the best treatments. While the highest N rates provided the greatest yields, it appears that 50 lb/acre of N in autumn followed by 50 lb/acre in early spring provides enough N for annual ryegrass growth.
While more N fertilizer would increase growth. Nitrogen fertiliser effects on perennial ryegrass crude protein and nitrate content J. Jacobs and F. McKenzie Department of Natural Resources and Environment, 78 Henna Street, Warrnambool, Vic.
ABSTRACT A study was undertaken to determine the effects of differing levels of nitrogen (N) (0 (N1), 25 (N2). Wheat is a grass widely cultivated for its seed, a cereal grain which is a worldwide staple food.
The many species of wheat together make up the genus Triticum; the most widely grown is common wheat (T. aestivum).The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around BCE.
Botanically, the wheat kernel is a type. Experimental set-up, sampling and analysis. Throughout the experiment in Table 1, the synthetic fertilizer, banded to the seed-bed at the time of sowing, was N-P-K (Cemagro Oy, Lohja, Finland) for the non-legume crops and N-P-K for the faba bean and white lupin were inoculated with the appropriate commercial strains of Cited by: 1.
Introduction. Soil organic matter, as indicated by C and N levels, is an important component of soil quality and productivity. Increasing soil organic matter through enhanced C and N sequestration can also reduce the potentials for global warming by mitigating greenhouse gas emissions and N leaching by increasing N storage in the soil.Carbon and N Cited by: 7.
