To Till or Not To Till

Seems like everyone is talking about no-till gardening these days.  This is the idea that if you inoculate your soil with bacteria and-fungi and layer enough enough compost and “duff”on the surface, that you can recreate the forest floor and avoid the tedium of digging our heavy East Bay clay.

While sheet composting, straw mulching  and shallow surface cultivation will work in the long run, it may not be the perfect choice for those who wish to garden in well amended clay soil in the next five years.  An integrated system of sheet composting,  double digging, single digging and amending with compost for the first few years will decrease the amount of time it takes to achieve an effective no-till system.

Here is a sample scenario:
Year 1:  Sheet mulch.

Year 2:  Double dig.  add compost and green manures, mulch with rotted straw, aged manures or other easily decomposable material.

Year 3 & 4.: Double or single dig with green manures or finished compost, mulch tops of bed with rotted straw,  aged manures or other easily decomposable material.

Year 4 or 5:  Start no-till gardening, continue to layer mulch on top of beds at each planting.

Integrated Pest Management: Compost Tea

 

Real Compost

WHY  Many of us now understand that healthy soil is the foundation of a healthy garden.  Beneficial bacteria and fungi in the soil partner with plants to bring them water and nutrients in exchange for exudates–sweet carbs that the plants release from their roots. Micro-organisms may also provides protection for the the plant in the root zone, by out-competing, killing and warding off less beneficial organisms. These very same bacteria and fungi can be brewed up in a tea and used to protect the above ground part of the plant. Spraying compost tea  on the leaves (called foliar feeding) inoculates the plant with beneficial micro-organisms that colonize the leaf pores to protect from  pests and pathogens.  Through this action, these same micro-organisms ensure themselves first dibs at decomposition dinner when the plant dies.  Foliar feeding can be done safely on a regular basis as a preventative, or at the first sign of a problem.

HOW  Put about a gallon of finished  living compost in a 5 gallon bucket.  Add a goodly dollop of molasses. Fill will water that has had the chloramine removed (a product for fish tanks and ponds will work well for this or use rain water). Place an air stone bubbler in the bucket and  run it for 24-48  hours (chloramine remover, airstone and small aquarium pump can be purchased in the fish supply section of any pet store).  When ready it smells fresh like compost. Strain through a fine cloth and spray it onto your plants.You may also use this as a soil drench to inoculate the garden beds or compost pile with beneficial microbes.
