How can nitrates be added to soil

So the effect you have observed is very important in some areas of the world. If farmers apply too much fertilizer, then it cannot be taken up be plants fast enough, or retained by the soil, so there is a danger that it will be washed through into the drainage water and get into the rivers. If this happens then algal growth and the growth of other water plants in rivers can be stimulated and the result is eutrophication. This is another reason for not applying too much nitrate.

Other extractants include 0. Refer to meter manual for the measurement unit setting. If the meter measurement unit is set to ppm NO3-N and ppm NO3- standard is placed into the sensor, 34ppm NO3-N reading will be displayed during calibration. Reference Bagshaw, J.

Except in very high nitrogen soils, the addition of extra nitrate will stimulate plant growth. Nitrogen fixers will take up nitrate from the soil, though they will still thrive in low nitrogen soils when the contribution from the symbiotic bacteria is more valuable.

Lupins are interesting in that their roots are able to extract more phosphate from soil than other plants.
