Getting your pH right!

The first step to getting the pH ( figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid, and higher values more alkaline) of your soil right, is to measure the soil’s pH. This is as simple of making a50/50 mixture of soil and deionised water, waiting 5 minutes and then dipping a pH strip into the mixture. These inexpensive strips are available from Plant Health Solutions in a form that measures finer graduations than normal. You are seeking a pH of 6.4 for optimal plant health growth. It is always important to try to understand why your soil is acidic or alkaline.

The best option is a soil test so there is no guess work involved. If you have acreage, a soil test can be worth its weight in gold. It is common to waste huge amounts of precious time, driving blind in an acreage gardening project, when a soil test would immediately clarify options and strategies.

If you can’t justify a soil test then these guidelines may assist you to diagnose the source of your pH imbalance:

If you have a light, sandy soil that is acidic, then you probably need a mixture of calcium and magnesium (dolomite) to correct the imbalance.

If it is heavier soil with more clay component then you probably need limestone to alkalise the soil and you might choose to include some gypsum to help break up the clay. If the soil is heavy and alkaline, then there is probably too much magnesium and sodium, so gypsum is the correction of choice.

Connecting with Calcium (Ca)

Connecting with Calcium (Ca)

Soil: Calcium opens up (flucculates) the soil, improving structure and allowing roots, earthworms, oxygen, water and microbes to move freely through the soil. Calcium is a critically important nutrient for the health of all life in the soil and it is also an important key to achieving the ideal soil pH of 6.4 (where nutrients are most available).

Alkaline soil with calcium carbonate deposits 

Plants: Calcium is often referred to as the ‘trucker of all minerals” in relation to its role mobilising other nutrients. Calcium sponsors cell division and hence it promotes root, stem, and leaf growth. Calcium is also a major mineral governing cell strength and associated disease resistance. This mineral often determines the quality of your fruit and vegetables and if you are seeking a problem-free garden then it should always be a first priority to address any calcium deficiencies.

Plant Deficiency Symptoms: Stunted root systems and a lack of vegetable vigour. Blossom end rot in tomatoes, capsicums and zucchini. Internal browning or blackening of celery, potatoes and brussels sprouts.

People: Calcium is one of the major minerals linked to bone health and skeletal strength but needs to be balanced with magnesium. It is also a key player in cell function and it regulates the uptake of minerals into our cells. Just as it influences plant uptake of minerals, calcium is an electrolyte important for cellular  messaging and the electric life of cells.

Animals : Calcium is a key element in maintaining good growth and bone health in animals. It is also important for healthy hormonal function and reproduction.

Common Forms: Lime stone contains 40% calcium and the finer ground the lime, the faster the response. Builder’s lime is called calcium hydroxide and it contains 30 times more soluble calcium than limestone so it can be used for “fast food”. However, this “hot” material should always be combined with humic acid or compost to buffer the burning potential. Dolomite contains 20% calcium and 10% Magnesium. Gypsum (calcium sulphate) contains 20% calcium and 15% sulphur. Guano contains 35% calcium and 12% potassium.
