 · Generally, crop residues of different crops contain 80% of Nitrogen (N), 25% of Phosphorus (P), 50% of Sulphur (S) and 20% of Potassium (K). Impact on soil properties: Heat from burning residues elevates soil temperature causing the death of beneficial soil organisms. Frequent residue burning leads to complete loss of microbial population.

There is competition on crop residue uses causing challenges in retaining adequate crop residues for full benefits of using residues to be realised. Among the crop residues management options fencing fields reduces the chances of crop residues grazing by free roaming cattle during the dry season.

 · The quotient R / 𝔪 R/mathfrak{m} is therefore a division ring, and in commutative case, therefore a field, called the residue field. In algebraic geometry, the residue field at …

The dry-land wheat production system of southern Australia is used to demonstrate the relative impacts and interactions of a range of pre-crop and in-crop management decisions on water productivity and a specific case study reveals how a novel genetic trait can interact with different management options to increase the water-limited yield of ...

 · In mathematics, the residue field is a basic construction in commutative algebra. If R is a commutative ring and m is a maximal ideal, then the residue field is the quotient ring k = R / m, which is a field. [1] Frequently, R is a local ring and m is then its unique maximal ideal. This construction is applied in algebraic geometry, where to ...

 · Residues are left on the soil surface between ridges. In-situ management of rice residues can also be done through Rotavators. Chopper is used for incorporation of the residue in soil, practiced for sowing wheat in Punjab. In-situ incorporation of crop residues enhances the soil nutrients like N, P, K and SOM.

 · Residue management is the emerging challenge for sustainable growth of Indian agriculture and environmental protection mainly in Indo-Gangetic Plains (IGP). Out of 620 MT crop residues produced annually in the country, 234 MT is surplus and 30% of it is contributed by rice and wheat. Approximately 16% of total crop residue being burnt, 62% …

 · Field residues The residues which are left in the field after the main crop is harvested are called field residues. When left in the field, these residues increase water holding capacity, control erosion, and add nutrients. They can be tilled back into the same soil. Ex- stem, leaves, stalks, etc. Post-harvest residues

 · Applying the construction above, we obtain the residue field of the point x : k ( x ) := Ap / p · Ap. One can prove that this definition does not depend on the choice of the affine neighbourhood U. [3] A point is called K -rational for a certain field K, if k ( x) = K. [4] Example Consider the affine line A1 ( k) = Spec ( k [ t ]) over a field k.

 · The answer is no. Consider K = Q ( 2, 3), and let p be any prime unramified in this extension. We will show that p cannot be inert. Assume the contrary, and let G be the decomposition group of p, which is necessarily the whole Galois group. There is then a surjection from G to the Galois group of the residue class field extension.

Consequently, with widespread use of combine harvesters, crop residues largely remain in the field and must be managed to provide the greatest advantage possible, especially for water conservation, erosion control, …

 · 1 Answer. Set T = R [ t 1, …, t n]. Our assumption that f is flat at x means that ( T / I) x is flat over R s. Now in 5.2/9, we take M ″ to be ( T / I) x since it is flat over R s, and take N to be k ( s) = R s / m s. We get the exact sequence we wanted: This justifies the statement " [the sequence] remains exact at x when tensoring over R ...

 · 1 Answer. These fields are precisely those which can be generated by a single element over their prime field. In fact, Q ( Z [ x] / p) is generated by the class of x, and conversely if a field F can be generated by a single element a over its prime field P, then let p be the kernel of Z [ x] → F, x ↦ a and observe that this induces a ...
