The phrase "application rate of compost" is correct and usable in written English.
It can be used when discussing the quantity of compost to be applied to a specific area, often in agricultural or gardening contexts.
Example: "The application rate of compost should be adjusted based on the soil's nutrient needs and the type of plants being grown."
Alternatives: "rate of compost application" or "compost application rate".
The improved growth characteristics of common bean plants produced as a result of increased application rate of OMF compost could be attributed to the enhanced decomposition of the OM and mineralization of nutrients (Abdelhamid et al. 2004; Ojo et al. 2014).
The topsoil in polybags was either amended with one of the cocoa pod composts at the rate of 20 g polybag−1 to correspond a compost application rate of 20 t ha−1 (Adejobi et al. 2011).
Total P concentrations were found as 21.8, 19.6, 17.2, and 15.5 g kg−1 with the sugarcane waste (SW) at the application rate of 0, 25, 33, and 50%, respectively, after 120 days of composting.
Application of RP-EC, with the ratio of 50 50 (RP Compost) and application rate of 800 kg ha−1 before 7 days of sowing, exhibited maximum growth and development, and can be highly recommended for optimum production of chickpea.
Also, the K content increased significantly (P < 0.01) from 401 to 565 mg kg−1 for the high compost application rates of 50 t ha−1.
Also, significant (P < 0.01) effect on electrical conductivity (EC) was found for the high compost application rates of 50 t ha−1.
Similarly, different rate of compost application to vegetable crops showed no significant differences in plant growth between high and low concentrations (Chang et al. 2007).
Changing the high rate of compost to a low rate of compost reduced the P2O5 balance by 45%.
Treatments were HC: high rate of compost; LC: low rate of compost; HM: high rate of manure; LM: low rate of manure; N0: a zero N control; and N100: 100 lbs sidedressed N/acre.
Treatments were HC: high rate of compost; LC: low rate of compost; HM: high rate of manure; LM: low rate of manure; N0: zero N control; and N100: 100 lbs sidedressed N/acre.
