Propagation and Fertilisers for Vegan Gardening Propagation and Fertilisers for Vegan Gardening Document Transcript

  • Vegan-Organic Information Sheet #1 (60p) Propagation and Fertilisers Growing with concern for people, animals and the environment Organic growing involves treating the soil, the growing environment and the world environment as a resource to be preserved for future generations, rather than exploited in the short term. Veganorganics means doing this without any animal products at all, which is not difficult when you know how. All soil fertility ultimately depends on plants and minerals - these do not have to be passed through an animal in order to work. Fertility can be maintained by plant-based composts, green manures, mulches, chipped branch wood, crop rotations and any other method that is sustainable, ecologically benign and not dependent upon animal exploitation. The guidelines below do not attempt to be fully comprehensive. The extent to which you adhere to any system really depends on you, your conscience and circumstances. We can only do our best with our available time and money. The VeganOrganic Network has now published comprehensive Stockfree Organic Standards, which are available to commercial growers and can also be used as a reference for home growers. Of course, no one person or organisation knows everything about the subject, so constant co-operation and updating of ideas and information is needed. Whilst conventional cultivation relies on synthetic chemicals and animal products, traditional organic production also generally relies on animal wastes and byproducts. Both involve the exploitation of living creatures, and the inefficient use of land, water and energy resources. Vegan-organic methods minimise these drawbacks. Many people who are not themselves vegan or vegetarian are coming to appreciate that animal-free growing is the most sustainable system: it is the future of organics. Make your own seed mixtures Mixtures for seed raising and potting can be time-consuming but are worth the effort. Seed mixtures need to drain freely, allow for aeration so that they can warm up quickly and have the ability to retain moisture. They need to be free from weed seeds, pests and diseases. A fine texture ensures that they make good contact with the seeds. They do not need high levels of nutrients, just enough to sustain the seedlings for four to seven weeks. •1•

Basic soil-free mix for seedling modules: • Two units plant-based compost. • Two units peat or peat alternative (see below). • One unit sharp sand or vermiculite or perlite. 3. Basic mix for free-standing transplant ‘blocks’: • Two units plant-based compost. • Three units peat. • Two units coarse sand or vermiculite or perlite. 2. Tolhurst Organic Produce has had success with: Photograph by Stéphane Groleau With home-made mixes it is impossible to be sure of the suitability of each batch, as the ingredients will vary from one season to the next. The following mixes should be suitable for raising seedlings but have not been rigorously tested: To the above three mixes you can add the supplements of: • 1/8 unit base fertiliser (see below). •2•
  • 1/8 unit seaweed meal. 1/8 unit lime. 1/8 unit colloidal phosphate. However, seedlings will still grow without these supplements. • • • The ingredients must be mixed well to form a uniform end product. First weigh out the units in buckets. It will be necessary to sieve coarse materials. Spread the contents on a clean, hard surface and mix in the same way that you would with cement using a spade or shovel, piling them up in a heap and turning it in. For larger quantities, it is worth using a cement mixer. Seed mixtures are better if they are six months old. sand. To the above mix you can add the supplements of: • 1/8 unit base fertiliser (see below). • 1/8 unit seaweed meal. • 1/8 unit lime. • 1/8 unit colloidal phosphate. However, plants will still grow without these supplements. Animal-Free Base Fertilisers Base fertilisers are very different from supplementary fertilisers in that the nutrients need to be released slowly so that they are available to the plant throughout its development. Supplementary fertilisers provide more readily available nutrients, e.g. potash boost from comfrey extract.

Use table 1 can be made at home by grinding them into a fine dust. The process of making alfalfa meal is described in peat alternatives. The base fertilisers in tables 2-4 are available commercially and the manufacturers have signed declarations that they are animal-free. Peat Alternatives Peat is to be avoided on ecological grounds. The journal New Scientist reported that 455 billion tons of carbon is sequestered in peat bogs worldwide. That is equivalent to about 70-75 years of industrial emissions, making conservation of peat bogs as important an issue as saving the rainforests. Coir dust, a mixture of short and powder fibres, is a by-product of the coconut fibre industry. Most coir (sold usually as blocks) comes from India, Sri Lanka, the Philippines, Indo- Contact nesia and Central America and is not encouraged because it is felt that this valuable source of organic material should stay within these countries. Plant-based compost with additives Plant-based compost is rarely used as the sole potting medium since it is too porous and has too high levels of soluble salts. Therefore it is prudent to add either perlite, vermiculite or sand (see the Iain Tolhurst recipe above). You can make the compost element yourself. Best composting practice involves: • using select ingredients, including crop wastes, grass clippings, legume-rich hays and straw; • mixing plant-based ingredients: 2 part ‘greens’ to one part ‘browns’; • composting plant-based materials and leaf mould separately; •5•
  • • building a heap of sufficient volume; at least one cubic metre; • turning the heap to assist with aeration; • monitoring temperature rises; • covering the heap or windrow to prevent it from becoming waterlogged; • allowing for the compost to mature (approximately one year). increases air space, and decreases the water-holding capacity of a mix making it a suitable alternative to peat. Its pH is generally 5.0 to 6.5, it is low in soluble salts, and it will probably require more nitrogen base fertilisers if used in a mix.

Adding minerals Mineral deficiencies (table 5) can be confused with plant diseases. The use of mineral amendments is not sustainable, because mining and the transportation is fossil-fuel intensive and opencast mining destroys local environments. At the same time, occasionally growers have to make compromises to avoid crop failures, which may justify one-off applications. However, if other recommended practices are followed for improving soil fertility (plant-based composts, green manuring, mulching and chipped branch wood), vegan-organic systems should not rely on mineral amendments. Good luck! Let us have any feedback or ideas of your own. Remember to use appropriate protective clothing by the way; lime and comfrey, for example, can irritate eyes and skin.
