Experience, judgement and intuition are valuable attributes to the farmer\producer in order to harmonise productivity and increase productivity economically.
Productivity is the rate at which goods are produced and the quantity produced in relation to work, time and money needed in the production process.
Optimal use is to exploit natural resources in such a way that the best products can be achieved without detrimental causes to these resources.
Efficiency can be sustained by ensuring that the relation between maximum production and cost effect is at the best level. There is no sense in applying more inputs than necessary as it will only increase the costs and not the production level.
If we want to stay on our farms and get rewarded for our work, we must farm with nature and we need to manage the natural resources in such a way that it will still be available for our children to enjoy the fruit of the land.
