WHAT YOU WILL DO
- Define terms related to the production and management of agricultural soil, such as manure, micorrhyzae, ameliorant, pore space, micro-nutrient, denitrification, ammonium fixation, chemo autrophic organisms, colloids, buffering capacity, leaching, compaction.
- Create a compost heap.
- Discuss ways that human activity can destroy soil structure.
- Explain how pH affects nutrient availability.
- Explain the function of different nutrients in soils/growing media, such at nitrogen and phosphorus.
- Analyse a soil test report in order to evaluate the soil for horticultural or agricultural use.
- Describe appropriate soil testing methods for different situations.
- Compare the use of organic and inorganic fertilisers in different situations.
- Develop a detailed nutritional management plan for a particular crop, following organic principles.
- Identify suitable earth moving equipment for different tasks, and the conditions of use.
- Explain various methods for assessing drainage at a site.
- Evaluate the use of earthworks to refurbish or improve a specific site.
- Research Environmental Protection Agency (or equivalent) recommendations for cleaning up chemical spills and for disposing of old household chemicals and their containers.
- Discuss advantages and problems of importing soil from elsewhere for crop production.
- Explain appropriate methods of stabilising an unstable or erosion-prone slope.
- Remove a soil profile, describe the different soil layers, and compare the effects of different soil treatments on the soil profile.
- Report on prevention and control methods for soil degradation, and development of sustainable soil management practices in a case study.
Soil Quality Can Change without You even Realizing
To the untrained eye, soils can undergo big changes, without looking much different at all. If you don't understand the soil fully; you can find that crop production quantity or quality, can change over the course of a year or two, before it is even noticed.
Consider Chemical Changes
Chemicals can end up in crop areas, often without us realising it. These can get there in several ways including:
- Spillages e.g. petrol spilled when using machinery or pesticides spilt during mixing.
- Leaching e.g. pesticides sprayed elsewhere may be washed off roads, driveways, footpaths, through water, etc. into other areas.
- Leaks e.g. machinery such as cars and ride on mowers, etc. may leak oil.
- Discards e.g. used water thrown out onto a crop growing are
- Overspray e.g. weed killer sprays carrying further than you want.
Overcoming Chemical Damage
The first step to overcoming chemical damage is to prevent it occurring in the first place. Leaky machines can be fixed. Spills can be prevented by taking more care, or by filling machines and preparing chemicals, such as weed killer, in an area where a spill won't be a problem. For example, on a driveway where any spilt petrol would evaporate before being washed into a growing area. Overspray damage can be avoided or minimised by being careful about not spraying on windy days and by making sure you use well maintained and suitable spray equipment. Damage from discarded chemicals can simply be avoided by being careful about what you throw out, and where you throw it.
Once damage occurs, however, there are a number of ways to overcome or control the amount of damage that might occur. These include:
- Carefully following any instructions relating to spills, etc. that may be supplied with the container in which the chemical was supplied.
- Seek further advice from the product manufacturer or from a local Environment Protection Authority (or its equivalent in your country).
- Leaching or flushing the contaminated area thoroughly with water. If the chemical is present in small quantities then this may reduce the concentration of the chemical to a level which will cause little or no damage. In some cases, however, particularly when heavy concentrations of the chemical are present, flushing the area with water will simply spread the problem.
- Replacing damaged soil - areas can be carefully dug up and removed. Fresh topsoil is then used to fill in the excavated area and the area replanted, seeded or re-turfed.
The soil removed from the damaged area should be disposed of carefully so that any chemicals won't create further damage.
- Contact your local council health officer or your state Environmental Protection Agency or your country's equivalent to find out where contaminated soil may be safely disposed.
- Soaking up spilt chemicals with absorbent materials e.g. sawdust, sand.
- Growing tolerant plants. Growing a plant can help extract and break down some types of chemicals.
When you understand soils and nutrition better, you will have improved your capacity to grow crops better. You ability to be a profitable and sustainable farmer of horticultural crops will be improved.
