Adaptation and Production of some Forage Species on the White Clay Soils of North Eastern China
Bibliographic record
Abstract
Grain corn, soybeans and wheat have been produced on the white clay soils of eastern Heilongjiang province of the People's Republic of China for about 40 years. Yearly plowing, cultivating and cropping led to a degradation in the physical and chemical properties of the heavy clay soil - a soil which constitutes 30 % of all the cultivated land in the region. This soil is characterized by a shallow loamy Ap horizon overlying a clay hard pan (Aw) (Zhang Zhi ui and Zhang Yuan fu, 1985). Forage crops have not been part of the rotation. To improve the soil physical and chemical conditions and to provide feed for the planned increase in the number of milk cows, a Canada-China project was begun in 1983-84. The aim was to develop a model grassland farming system which would demonstrate the role and value of forage in soil improvement and which when marketed through milking cows would result in a economically sound enterprize. However, few data (Paan Chaobang, 1984) were available on the adaptability or use of the species and cultivars of forage crops in the region. The first step in the project was to develop the forage component of the grassland farming system. The purpose of this paper is to outline the results of the forage research conducted at State Farm 352 from 1983 to 1988.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
