Grant improved his long-term production through Salinity Mapping.

By Gary Hutchinson, on April 15th, 2011

This is some salt scald areas of Grant Wardle’s Straithairlie farm near Boyup Brook in Western Australia.

Salinity affects nearly 50% of farmed land in WA. Note how the salt at the surface has eliminated most of the vegetation except for some hardy, salt-tolerant grasses.

Grant’s challenge was how to restore vegetation along . . . → Read More: Grant improved his long-term production through Salinity Mapping.

How is the pH of my water affecting my farm's productivity?

By Gary Hutchinson, on April 1st, 2011

Water’s acidity, neutrality or alkalinity is denoted by pH. It is measured on a scale of 0-14 with 7 being neutral. Readings below 7 are acidic and above 7 they are alkaline.

Water with any reading between 6.0 and 8.5 is considered suitable for irrigation. Also, water outside this pH range used in spray . . . → Read More: How is the pH of my water affecting my farm’s productivity?

Is salt in my water affecting my farms productivity?

Salinity is one of the biggest issues with water quality.

You can easily test the salinity of water with a Salinity Meter which measures the electrical conductivity of the water. As the salt level of the water increases, so does the conductivity.

Water salinity measurements are expressed as microsiemens per centimetre . . . → Read More: Is salt in my water affecting my farms productivity?

Assessing your annual water needs

By Gary Hutchinson, on March 31st, 2011

A key water resources question that every farmer should ask himself is How much water do I need for my property?

The annual water needs for a rural property will vary depending on where the property is located, the type and number of livestock held, crops grown and the number of people dependent on . . . → Read More: Assessing your annual water needs
