2. Organic fertilizer: Add nitrogen (N) naturally to the soil - Salt the soil - Keep the soil alive - Never plow


1. Root tricks

Loosen hard and unfertile soil reconstructing it

When nothing grows, the soil can be "repaired", with organic contents, with humus:
-- Cultivating taproot pioneer plants: fenugreek, dandelion break up the soil [web26]
-- In rare cases one has to dig, then mulch and cover to protect the soil animals [web26]
-- Put compost [web26]
-- One can plant plants that produce a lot of green mulch biomass, so that the leaves then rot to humus [web26]
-- Legumes (beans) give nitrogen to the soil nitrogen [web26]
-- Never step on the ground of a garden bed or air and water channels will be destroyed [web26]
-- Earthworms distribute more fresh humus in the bed, earthworms dig well the earth  [web26] [without harming to the roots]

Deeprooters - flatrooters

Plants have roots of different lengths, which can be "used" as needed.

Here are some plants with root lengths of over 50cm:





sorted by alphabet: sorted by root lengths:


-- Alfalfa to 5m
-- Buckwheat up to 80cm
-- Clover: crimson clover up to 100cm
-- Clover: king's clover to 3m

-- Grass: German ryegrass up to 80cm
-- Lupins blue / white to 3m
-- Lupins yellow to 3m
-- Marigold to 80cm
-- Oil radish up to 1.5m

Taproot pioneer plants - the soil looseners
Installing a new garden or overtaking an industrially destroyed soil, one has to plant taproot pioneer plants that break up the soil [web26] [and pull up minerals]:
-- Fenugreek [web26]
-- Dandelion [web26, web28]
-- Daikon [web28]
-- Burdock [web28]

Deeprooters - examples

Factor Density of Seeding: Roots develop differently depending on the density of the planting: the more densely planted, the fewer the roots can develop:

Deeprooter food forage plants for rooting the subsoil to prevent compaction layers

A root of any plant will only develop depth and nourish many nutrients when the soil is loose. In order to keep the soil loose, it is sometimes necessary to grow fodder plants with deep roots that loosen up the soil. Thus, degraded soils are "repaired", the roots "build" new "channels", the soil is enriched with humus, and diseases and pests are destroyed [by the new penetration of the soil population into the lower layers] [web52].

Deeprooter food forage plants in the "USA": Prairie smoke, Whyetia scabra, Lupines, bluebunch wheatgrass

Desert Mule's Ears (Wyethia scabra)
Lupine: Velvet lupine (Lupinus leucophyllus)

Fernleaf biscuitroot (Lomatium dissectum)

Short roots:

Alfalfa and lupine, for example, are such fodder plants, have deep roots, "root through" the soil with strong taproots and break up "compaction layers". Alfalfa requires calcareous soils. Lupins also grow on sandy soils that are slightly acidic [web52]. Cultivating alfalfa or lupine at regular intervals improves and loosens the soil for vegetable crops. In other words, roots of other plants can more easily penetrate into the subsoil in dry years and tap water reserves and nutrient reserves there. Harvests increase by almost 100% [web52]. If there are compaction layers and drought together, cereals die for example. Deep plowing does not make sense, it even destroys the soil's carrying capacity and also causes erosion [and destroys soil animals] [web52]. Alfalfa is a pronounced bumblebee plant [web54]. Lupines have a side effect: they also enrich the soil with nitrogen. Therefore, one should use the lupins only in agriculture and never plant in the garden or on a grassy meadow, otherwise a poor meadows will soon no longer be a poor meadow, the flowers disappear and only "fat grasses" will dominate [web53].

On nutrient-poor meadows NO nitrogen-enriching plants must be planted such as e.g. the lupins, otherwise the meager meadow is soon no longer meager, and the flowers then disappear, but then only "fat" grasses will dominate:

2. Organic fertilizer: Adding nitrogen (N) naturally to the soil

It is a complete nonsense to produce fertilizer from bird manure, selling it in an expensive package selling it for an expensive price. Adding nitrogen is much easier:

Sawdust are organic fertilizer mulching (3 inch thick layer) [web22], causes in the garlic field 250% larger garlic tubers than without sawdust [web55]
Wood chips are organic fertilizer [web22]
Horn shavings are organic fertilizer: Horn shavings are grated from cow horns, bull horns or from the hooves. Horn shavings contain between 12 and 15% nitrogen (N), along with some phosphate, sulfur and potassium (below 1%). Horn shavings are a universal fertilizer [web40].
Horn shavings have to be decomposed first by the microorganisms in the soil before the plants can absorb the contained nitrogen (N). Horn shavings work for about 1 year, horn grit about 1 month, and horn meal for a few days [web40].

Eggshells in mixer as a powder is organic fertilizer

Eggshells are a lime additive to the soil [web02]: One can crush egg shells in the blender and sprinkle the eggshell powder on the planting beds as a calcium boost [web44]

People with houseplants or with only "normal" planting beds for irrigating, can mix the eggshell powder with water and then irrigate the houseplants, this works faster than distributing the egg shell powder by hand [web43]

Primary rock flower as organic fertilizer: gives the soil plenty of minerals [web41]
Shell limestone as organic fertilizer: gives the soil minerals - can be purchased as a dietary supplement for chickens and dogs [web42]

Salt the soil

-- plant pecan trees, e.g. in combination with blueberries [web22]


Keep soil alive

New Zealand White Clover: For a long-lasting vivid circulation, plant New Zealand white clover - it's a low growing, nitrogen-binding, drought-resistant perennial plant that likes to be mown [web22].

Never plow

Plowing and digging destroys the soil structure and UV radiation kills ground animals: turning the soil causes deeper layers of soil to be exposed to the sun, exposed to UV rays and the sun's heat. The soil organisms (soil biota) which are living without sunlight are killed in the sunlight and a new population has to form again so the soil is dead for a wile and pests can intrude without resistance [web26].

By forming panicles in the field for planting, the plants form deformed roots and rarely form lateral shoots [web58].


Snails and slugs

Who is eating the snails and slugs?
A garden should have a drywall where the beneficials live that eat the snails and slugs: salamanders, hedgehogs, snakes.

The hunt for snails and slugs from the drywall (see: Wildlife at / in the drywall)
Alpine salamander eats snails and slugs - blindfoots eat slugs - and ducks eat slugs coming from the pond

The western and eastern emerald lizard feeds snails, forest lizards eat snails, possibly the Croatian mountain lizard - hedgehogs eat snails - toads (common toads and green toads) eat snails at night - wolf spiders eat snails at night.

When there is no drywall in the garden or on the farm, you can protect vegetables with a snail / slug guard on the rim (made of metal) or with a snail collar (made of plastic). In the end, however, the snail / slug collar costs much more than creating a drywall in the garden and restoring the ecosystem. Leaves should be left. The combination of drywall and heap of leaves / foliage attracts the beneficials, who then eat the snails and slugs. Even bugs hibernate in the drywall, which are then eaten by lizards ...

Slug pellets also poison the beneficials - thus slug pellets MUST NOT BE APPLIED but have to be rejected.


Collect seeds

Collect seeds and put shields to the plants: "Identify plants from which you want to store seeds, or remember the source, which is a matter of course for spring sprouting or direct sowing, but it is important to remember to label in midsummer. Refresh them as the sun and water will fade in. Sit in the garden for a few relaxing minutes and update faded labels, making a note of the generic name, variety, seed source initials and sowing date. Do not rely on seed envelopes on a stick." [web22]
