- The high cost of chemical fertilizers, herbicides and pesticides. This has led to an epidemic of suicides and bankruptcies by rural farmers in many developing countries.
- The high cost of transportation to haul chemical fertilizers, herbicides and pesticides to rural areas from urban factories.
- In order to maintain productivity, ever increasing amounts of chemical fertilizers are needed, until it is simply no longer profitable for the farmer or the forester.
- Dead soil and a loss of the soil’s microfauna, including earth worms, soil fungi and more, with the resultant loss of biodiversity as other creatures in the food chain are affected, all the way up to humans.
- The loss of honey bees due to the use of herbicides and pesticides, leading to a pollination crisis in many places.
- Agrochemicals, especially when used in tropical soils with poor nutrient retention, can experience losses as bad as 90%, which is a very bad investment, with those chemicals ending up in the ground water and rivers.
- Agrochemicals do not make the nutrients trees and plants need bio-available in the same way that earth worms, fungi and other microfauna make those nutrients bio-available.
- It doesn’t take a genius to realize that agrochemicals cause environmental contamination.
- Crops, be they forestry or food related, are less resistant to plagues and diseases, requiring the application of other chemicals before they can be harvested or appear on your plate.
- Serious health effects on humans. For example, Argentina is now suffering from an explosion of agrochemical related illnesses.
- The constant use of agrochemicals causes the soil to be more compacted, asphyxiating the soil.
- The constant use of agrochemicals results in the soil losing its cationic exchange capacity (CEC – see Part 1), in other words it further aggravates problems with soil nutrient retention.
- Agrochemicals cannot be consumed by earth worms and other beneficial creatures living in the soil.
- The quality of products being produced is poorer, especially where foods are concerned (flavor, ingredients etc.)

- The use of local resources to make fertilizers at a significantly reduced cost.
- No costly transport of fertilizers over large distances.
- Higher labor requirements resulting in greater local socioeconomic benefits, but still cheaper than the purchase of agrochemicals and their transport.
- Soil that is alive and healthy.
- The avoidance of environmental problems and degradation.
- Less plagues and diseases affecting one’s trees or crops.
- Production results that are equal to those achieved with agrochemicals, and superior when done with soil amendments like biochar (see Part 2).
- Organically managed soils have significantly better cationic exchange capacity (see Part 1) and soil nutrient retention.
- The forester or farmer is producing significantly less residual solids and contaminating garbage.
- Virtually all nutrients produced in natural silviculture and organic farming are bio-available to the trees and plants.
- Healthy organic soils have better water retention in the dry season.
- Organic fertilizers do not burn the roots of the trees or plants, a common problem with chemical fertilizers.
- A lot less soil acidity, especially in tropical soils, with the use of organic materials.
- Soils that are organically managed are less compacted and better aerated, which in turn assists soil microfauna.
- Forestry and agriculture that is more profitable.
- Plantations and farms which are more sustainable and Earth-friendly, with healthier humans living and working in them.
