Why should we not till soil?

Since tillage fractures the soil, it disrupts soil structure, accelerating surface runoff and soil erosion. Tillage also reduces crop residue, which help cushion the force of pounding raindrops. Without crop residue, soil particles become more easily dislodged, being moved or 'splashed' away.

Why should you not till soil?

Tilling aerates the soil in the spring

Wrong. Tilling breaks apart air and water pockets that have been naturally created by microbes, earthworms and other insects, causing compaction and lack of airflow for root systems. These creatures are natural tillers and the only tillage system you need.

What happens if you don't till soil?

The roots left in place in a no-till garden will decompose over time, providing free organic matter and nutrients to the worms, microorganisms, and other detritus-eaters in the soil – which in turn feeds plants!

When should soil not be tilled?

You should always check the state of your soil before tilling. Avoid tilling in wet soil as soil compaction can occur and lead to poor root penetration in the growing season. If it rains, it's best to wait a few days to allow soil to become semi-dry.

What are the benefits of no tilling?

No-till adoption also reduces soil erosion, increases soil biological activity and increases soil organic matter. These benefits can lead to additional economic gains for farmers over time.

Till vs. No Till Gardening - Pros

Why is tilling a problem?

Since tillage fractures the soil, it disrupts soil structure, accelerating surface runoff and soil erosion. Tillage also reduces crop residue, which helps cushion the force of pounding raindrops, and disrupts the microorganisms in the soil, leading to poor soil health.

What are the negative impacts of no-till?

With no-till a farmer has lost the ability to mechanically control weeds through tillage. There is a risk of carrying over plant diseases when crop residue is not incorporated into the soil after harvest. This can act as a host for disease and can infect the following crop.

What is an alternative to tilling?

You can either bury your cover crop with a heavy sheet of mulch, or you can cut them immediately above the crowns (this works well with plants that are tough to kill without tillage, like vetch or rye). You can even use chickens to naturally till in your cover crops!

Is tilling or no tilling better?

No-till tends to increase soil organic matter in the top several inches of the soil. On the other hand, tillage can act to bury carbon and increase its storage. That said, overall, intensive tillage tends to burn up much of the soil organic matter, more so than no-till."

What is the disadvantage of tilling?

The downside of tilling is that it destroys the natural soil structure, which makes soil more prone to compaction. By exposing a greater surface area to air and sunlight, tilling reduces soil's moisture-retaining ability and causes a hard crust to form on the soil surface.

How can I make my soil better without tilling?

The secret behind any no-till garden lies in regular mulching with organic matter. Mulches cover the soil's surface, protecting it from erosion, locking in soil moisture and suppressing weeds. As they rot down they add fertility to the soil while at the same time improving its structure, without the need to dig.

Is it better not to till your garden?

The choice to till your garden ultimately should depend on the state your soil is in. No-till gardening can reduce the loss of soil and moisture and spare you some physical labor. However, to ensure the long-term health of your soil, don't be afraid to dig deep, especially with the help of a tiller.

Does tilling protect soil?

Unfortunately, in the long run, tilling does more harm than good. Here's why. Tillage loosens and removes any plant matter covering the soil, leaving it bare. Bare soil, especially soil that is deficient in rich organic matter, is more likely to be eroded by wind and water.

Why are people against tilling gardens?

Erosion. Tilling lifts and loosens the soil, which makes it susceptible to erosion. The organic matter atop it – both living and decaying — helps to keep the valuable, nutrient-rich topsoil in place. When we till the garden, we uproot everything and turn that organic matter topsy-turvy.

What are the disadvantages of till farming?

Little erosion control with more operations. High soil moisture loss. Destroys soil structure. Compacts wet soil.

What is tillage and why is it bad?

Tillage results in two self-perpetuating cycles: it burns up soil organic matter (OM) necessitating the addition of more, and it stirs up weed seeds, necessitating yet more tillage to kill the weeds. Conventional farming “solves” these two problems in a manner that is not sustainable.

What can farmers do instead of tilling?

In conventional systems, farmers can practice no-till by using chemical herbicides to kill cover crops before the next planting. Organic no-till, on the other hand, uses no synthetic inputs. Instead, small-scale organic no-till farmers use hand tools, like hoes and rakes.

How effective is no-till farming?

In fact, no-till farming can reduce soil erosion by more than 80 percent, which has the added benefit of protecting water quality by keeping sediments on the land and out of bodies of water. Soil health can be improved even further when no-till is combined with cover crops and other sustainable practices.

Does tilling cause more weeds?

Tilling causes more weed issues than it ever helps to eliminate. Every time tilling occurs in the soil, thousands of weed seeds laying on the surface of the soil are driven into the soil.

Does tilling dry out soil?

Effects of Tillage on Wet Soil

Tilling and soil health go hand in hand when they are accomplished on dry soils. This beneficial mechanical process brings in air, water and nutrients to needy roots. Tilling wet soil squeezes together soil particles and inhibits seed germination and young root growth.

Does tilling get rid of roots?

Tilling is needed if you are mixing amendments into the soil. It is also helpful if you have severely compacted soil that needs to be broken up or any type of soil that needs to be broken into finer bits for planting seeds. This process also removes weeds and undesirable roots from the soil.

Does tilling reduce organic matter?

It has been well documented that increased tillage intensities can reduce soil organic matter in the topsoil due to increased microbial activity and carbon (C ) oxidation. The potential loss of soil organic matter due to tillage operations is much higher for high organic matter soils than low organic matter soils.

Is no-till farming a threat to biodiversity?

Unsuitable soil management in agriculture is known to results in the deterioration of soil health and the decline of biodiversity.

What are the advantages and disadvantages of no-till farming?

Does no-till farming increase soil fertility?

Benefits of No-Till Farming

The no-till farmer will see an increase in the organic matter of the soil, and a decrease in the amount of erosion. More organic matter and less erosion mean more fertility, less fertilizer, and higher yields.
