Weeds and Soil

A weed is considered as a nasty plant, yet we don't know how they survive and they grow profusely. Weeds, environmentally, are the principal plants to grow in nutrient less,nutrients insufficient soils that is in poor soil. Most weeds develop in soils that are high in nitrates and are microorganisms commanded soils. By observing the kind of weeds that grow on your soil, will give you sense of what conditions are constraining. The genuine reason behind weed growth is to improve the biology of soil. Numerous weeds go about as authorities of inadequate soil minerals. The compelling force of nature doesn't care for uncovered soils, so she discovers something to develop (weeds) that improve soil so different plants can develop,thrive, adapt for correcting imbalanced nutrient in soil.

Each plant is a pointer of the conditions that exist in that field and demonstrates why some agronomic yields (corn, groundnut, Paddy, Beans) development may endure. Weeds provide us some insight into what variables are either restricting or in overabundance.
  • An overwhelming growth of leguminous weeds means soil is suffering in nitrogen levels.
  • Severe growth of Non-leguminous weeds means excess of nitrogen levels in soil.
  • Deep tap root weeds is indication of compact soil.
  • Shallow roots indicates soil is prone to erosion.

Weeds undergo successive rotation from grasses, to bushes, to forest and afterward timber lands and this is called characteristic succession.

Calcium enables soil to disperse while magnesium will generally tie soils firmly together. These ineffectively depleted soil begins to hull and split and there is an absence of soil air passage in the mud leading to anaerobic (absence of oxygen) conditions.

Difficult to control weeds like Wild Amaranthus, water hemp, and Horseweed flourish in low Ca and P fields with high K and low humus. Amaranthus palmeri improves on exceptionally permeable soils with high sulfur (S), iron (Fe), and copper (Cu) and lower dampness (sandier soils) while water hemp grows ineffectively depleted clay soils. Horseweed need high Mn yet does well on compacted soils with anaerobic (low oxygen) field conditions. Amaranthus palmeri and Horseweed grows well in exposed upset soils without rivalry, so planting an cereal crop ahead of schedule with radish reduce or diminish them successfully .

Numerous weeds shield our topsoil from rain, wind, and sun, particularly when the green cover is poor. By giving a covered vegetation, weeds empower useful soil creatures to be dynamic at the surface, storing their supplement rich droppings and additionally going about as natural control operators against different pests/bugs. Many weeds, especially perennials, have broad root frameworks that infiltrate deeply into the subsoil by breaking hard soil and helps the roots of main crop to penetrate easily to depth.

Weeds helps to break up the subsoil additionally improves drainage condition of soil.

Deep entrance by their foundations frequently empowers weeds to collect different components from the subsoil, especially trace nutrients, and transport them to the top soil. Through the weed's ensuing demise and decay, these components become accessible to main plants with less broad root.

Weeds have likewise been utilized as markers of the of ground water quality.Different weeds are adjusted to various scopes of ecological factors and can develop just where their specific needs are met. For instance, certain species, for example, perennial broad leaf weed ex:German Knot-grass, are bound to corrosive soils, while others are constrained to normal soils.

A significant number of my observations depend on general perceptions and individual field circumstances may change enormously. Many cereals, radish, and sorghum or Sudan or multi-species spread yields can out contend numerous weeds and have an allelopathic (normal herbicide) impact on most weeds. Keeping soils sound by and large results in better soil supplement status, less weeds after some time, and more beneficial yields.

Five Layer Shri Palekar Ji Model - 36*36 model for full 1 acre

Huge trees, for example, Mango, Jack-fruit, Jamun, and Amla ought to be planted 36 feet separated.
Guava, Chikku, Lemon and Pomegranate saplings can be planted in the middle of the mango plants at a separation of 18 feet.
Papaya, Drum-stick, Banana that involve lesser space ought to be planted in a space of 9 feet between the second arrangement of trees recorded previously. The above plants ought to be planted along a similar column over the plot of land leaving space to develop a single assortment of vegetables, millets and so forth on each bed.
separate 1 section of land into a break even with squares of 36ft X 36ft. In each piece of 36 ft x 36 ft ( which is additionally separated into four 9ft X 9ft sub-squares) We can grow around 170 trees, in that 9ft x 9 ft part of the land (one sub-square). Plant 1 Banana Tree, 4 Arecanut Trees, 4 Black pepper Creepers getting on Arecanut trees, 2 Coffee Plants, 2 Glirsedia Trees, 2 Venella Creepers hopping on Glirsedia trees and 32 Ginger Plants …

Dhabolkar method of green manuring

Mr.Dhabolkar, an organic farming expert in Maharashtra, has proved the efficacy of green manure method, which helps to return to the soil many times more nutrients than what we take from that same soil. The first step, therefore, to enrich the soil organically is to grow a variety of crops on the land and then plough the green matter back into the soil. Using this method it is possible to enrich the depleted soil in just two hundred days. Even land that has been depleted of all nutrients due to chemical farming can be resuscitated in this manner.By growing the following crops for 50-60 days and then ploughing them in-situ we add balanced nutrients and micro-nutrients to the land. The soil will become enriched in less than a year and micro-nutrient deficiency is eliminated.

The following quantities will suffice for one acre.
Choose four of each of the following types:(One from category total five)

1. Grains: 5Kg (Example: 1 kg Sorghum, 500 gms Pearl millet, 250 gms Foxtail millet, 250 gms …


Indian humped cows have suryaketu nadi(vein) passing through hump which absorbs all cosmic energies( 33 CRORES of gods & goddess reside in cow). As per astrology SURYA( which rules soul) and KETU (Lord of Moksha). Means Humped cow helps soul attain moksha(liberation)? We need to remember, we have nine planets starting from Sun and ends with Ketu.

After death soul should cross VAITARINI RIVER(which is very difficult) if we donate a cow before death. we can cross this river with the help of cow tail. This sentence describes that we need to protect cows and pass them to future generations.

The human body has 7 CHAKRAS(energy centres) described in Ayurveda and having 72000 nerves. Same like we can assume cow have 33 crores of nerves and all connected to suryaketu nadi( same as our backbone)? IDa-PIngala are the main nerves which connected to Left/Right nostrils and pass oxygen to all parts of human body, eliminate toxins as co2. In the same way, Surya-Ketu nadi was functioning in Cow? Sur…
