The phrase "amendment rate" is correct and usable in written English.
It can be used in contexts related to legal, financial, or policy changes where a specific rate of amendment is being discussed.
Example: "The amendment rate for the proposed legislation was set at 5% to allow for necessary adjustments over time."
Alternatives: "revision rate" or "modification rate".
Model parameters were responsive to varying soil characteristics (pH, C, N, C N), amendment N C, amendment rate, incubation temperature, and N additions.
We conducted a glasshouse pot experiment to investigate the effect of alum-based DWTR amendment rate and P fertilizer placement method on Brassica pekinensis growth and As, Cd and P uptake under controlled conditions.
Results showed that a DWTR amendment rate of 2 wt% coupled with banded P fertilizer application resulted in the greatest B. pekinensis aboveground tissue biomass, along with a reduction in plant tissue Cd or As concentrations not significantly different from higher rates of DWTR amendment.
Results indicated that sodium in effluent was increased with increasing amendment rate and PV of leaching water.
In the contaminated soil sample, at the highest phosphate amendment rate (198 mg P L−1), Bray extractable As was approximately three times greater than in the non-phosphate amended soil (Fig. 6).
TCLP extractable Pb appears to become asymptotic as P amendment rate increases, suggesting that there is a maximum immobilization potential of P amendment under the conditions of these experiments, and that higher P amendment rates will not decrease TCLP extractable Pb.
Silva, J. D. C. et al. Effect of different tannery sludge compost amendment rates on growth, biomass accumulation and yield responses of Capsicum plants.
The main objectives of this research were to determine the effects of interactions among irrigation strategies and substrate amendment rates on cucumber (Cucumis sativus L). physiological traits, fruit quality and yield in a soilless culture system in greenhouses.
A 6-year field experiment was conducted to evaluate soil phosphomonoesterase activities, kinetics and thermodynamics during rice growth stages after consistent swine manure application, to understand the impacts of swine manure amendment rates on soil chemical and enzymatic properties, and to investigate the correlations between soil enzymatic and chemical variables.
However, the amendment rates were not significantly different from control soil at 12 WAI.
But there were no significant differences in control and the amendment rates at 4 WAI.
