Getting your soil Ph level in line with your plant Ph level will help you grow the best plants.

Adjusting your soil ph level in line with your plant Ph level needs will help you produce the best quality and taste for that plant. If your garden ph level is off your plants won’t be able to use the available nutrients. The impact on primary, secondary and micro-nutrients availability is significant.

Understanding the impact of an out-of-whack soil ph level can be compared to taking a shower. If the water is too hot it feels like it is burning you. Likewise if the water is too cold it is freezing. You adjust the water temperature to make it just right.

Adjust your growing medium to the correct soil ph level of the plant(s) you grow. This temperature comparison is also true with watering your plants.

It is the same with plants, but they can’t move. If the growing medium it too acidic or alkaline their growth can be stunned, produced little or no fruits or even die. It can take years to get your ph level right.

You may need microorganisms to convert many minerals to usable soluble nutrients. It can also take a considerable length of time for the minerals to migrate through the soil column.

You should always test your growing medium to decide what the medium needs for your best soil ph level. Contact your local farm bureau extension on how to sample your growing medium and find out who provides the best cost for the tests.

The bonus of a soil test vs. just ph level is that you will know what nutrients you have or not have allowing you to fine tune your growing medium. You will want to test the medium several months before planting to make sure enough time to change your growing medium before planting.

Acidic Soil Example

Adjusting the soil ph level takes time as much as several months depending how out of balance the soil is. The soil of the Amazon River basin is highly acidic. The acidity limits what plants can grow.

Amazonians were modifying their garden sites soil ph level over 2,000 years ago. The gardens produced enough fruits and vegetables that support populations up to 30,000 along the river banks.

When the Spanish explored the Amazon river basin the diseases the brought reduced the native population by 80%. After 500 years of untended gardens are producing three crops a year. These gardens still survive today. See National Geographic Explorer’s “The Secrets of El Dorado.”

Taking the successful lessons from the Amazon natives to use of organic materials to bring the growing medium to a neutral ph level. We have applied the lessons to The Tuxedo Gardening System.

The Tuxedo Gardener Growing Medium

soil ph level Organic Fertilizers
Organic Fertilizer is used to grow huge amounts of food from a raised bed garden in a Willamette Valley, Oregon site. Plant ph level requirements are met in The Tuxedo Gardener’s growing medium

The natural decomposition process of the organic alfalfa, straw and compost begins acidic. In a short time it quickly evolves into a neutral ph level.

Dolomite lime powder vs Sulfur to lower ph levels

Use Sulfur to lower growing medium ph levels. To decide how much sulfur to use check out this site.

You want to use a mask when applying any minerals due to  health hazards and wash thoroughly after applying.

Make sure you use Dolomite and not Quick lime. Quick lime will destroy organic material ie. You.

Dolomite lime contains calcium (calcium carbonate) and magnesium (magnesium carbonate). calcium and magnesium are also essential nutrients to keep blossom end rot at bay. To decide how much lime to use check out this site.
