Soil Results

In 2018 Teagasc analysed a total 45,157 soil samples comprising of dairy, drystock and tillage enterprises. 42,067 soil samples were from grassland farms with 21,676 from dairy farms and 19,801 soil samples from dairy farms. The following is a summary of the main changes for soil pH, phosphorus (P) and potassium (K) in 2018.

Dairy

  • 59% of soils with a soil pH >6.2
  • 56%of soils at P index 1 & 2 (4% Decrease)
  • 48% of soils at K Index 1 & 2 (11% Decrease)

Drystock

  • 43% of soils with a soil pH >6.2
  • 63%of soils at P index 1 & 2 (4% Decrease)
  • 52% of soils at K Index 1 & 2 (10% Decrease)

Soil pH levels improvements have remained relatively stable in 2018 (see figure 1) with 54% of soils in the optimum range for soil pH on grassland soils.

Figure 1. Proportion of soils analysed which fall into each soil pH range across all farm types. Based on total of 223,000 soil samples analyzed by Teagasc between 2014 and 2018.

 

Soil P levels show small improvements on both dairy and drystock farms with a 4% decline in soil testing at soil P index 1 & 2. Soil K levels show significant improvements of between 10 and 11% in 2018. This maybe a reflection of the targeted application of organic fertilisers plus the application of straight potassium as muriate of potash (50% K).

Overall all farm enterprises have made progress in relation to soil fertility over the last couple of years. Soil fertility on dairy farms showed that approximately 18% of soil samples with the optimum mix of pH, P and K for grass production. Drystock farms showed that 11% of samples with good overall soil fertility. These poorer results on drystock farms may be influenced by a number of factors such as lack of profitability, lower fertilizer use, lower feed demand and need to maximise grass production especially where stocking rates are low.       While the majority of these overall soil fertility improvement has resulted from positive changes in soil pH across all farming enterprises there are also indications that soil K, and possibly P, are also improving.
