What is a good crop productivity index?
What is a good crop productivity index? CSR2 ranges from 5 (least productive) to 100 (most productive). CSR2 lets farmers and landowners easily compare productivity across farms. For example, a farm with an average CSR2 of 85 is significantly more productive than one with an average CSR2 of 60. How do you define productivity? Productivity […]
