Soil salinity refers to a high concentration of salts in the landscape, mainly common salt or sodium chloride (NaCl), which has a negative impact on soil and water quality... A related protein in the test plant Arabidopsis, AtNHX1, has a very well-characterised role in salt tolerance... A deeper understanding of the mechanisms underlying this salt tolerance will be critical to the use of NHX proteins in producing transgenic salt-tolerant crop species...

pH measurements taken from wet and dry soils can vary if we measure the pH in water because the soil has a "background" salt concentration... To minimise the effect of salt concentration in soil on pH values, pH is now measured in 0.01 molar calcium chloride... As soil testing for phosphorus was originally conducted on the top 10 cm of soil, so the soil pH was only measured for the top 10 cm...

In order to maximise the benefits of fallow sprays, Dow AgroSciences' Rob Buttimor says they need to be managed to the same degree as in-crop sprays so growers do not end up with a mess in the spray tank... "Growers using 2 percent AMS in soft water are effectively wasting their money," Mr Buttimor says... By adding lots of other ions to the spray tank in the form of hard water or soluble liquid herbicides, it neutralizes these charges and the oil droplets can come together to form large oil droplets, oily gels or general glug that will float to the top or sink to the bottom of the spray tank...
