Developing pedotransfer functions to harmonize extractable soil phosphorus content measured with different methods: A case study across the mainland of France

A simplification of Ghani's method for the fractionation of soil phosphorus has been used to study relationships between soil and plant phosphorus in field and pot-culture experiments.In pot-culture experiments with red-brown earth soils (pH 5·6–6·1) wheat derived approximately 60% of its phosphorus from the fraction of soil phosphorus soluble in 2·5% acetic acid-1% 8-hydroxyquinoline and 30% from the inorganic fraction soluble in 0·1 n-sodium hydroxide, even although the amount of acetic acid soluble phosphorus present in these soils was only about half that present as inorganic alkali soluble. Very little use was made of organic phosphorus.In field experiments with similar soils there was a correlation between the percentage phosphorus in the plant material and the acetic acid soluble, the inorganic alkali soluble, and the sura of these two fractions of soil phosphorus. The sum of these two fractions was also correlated with the amount of phosphorus taken up by the crop.In pot-culture experiments with a wider range of soil types there was good correlation between the total extractable inorganic soil phosphorus and both the phosphorus content of the plant and the phosphorus uptake. Correlations between individual inorganic extractable soil phosphorus fractions and plant phosphorus were influenced by the pH of the two groups of soils examined.

The pot experiment was established in vegetation hall in the year 2015. Spring barley, variety KWS Irina, was grown. Two different soils – chernozem from Brno (with a low phosphorus content and alkali soil reaction – 7.37) and haplic luvisol from Jaroměřice nad Rokytnou (with a high phosphorus content and slightly acid soil reaction – 6.01) were used for comparison. The rates of phosphorus in the form of triple superphosphate (45 % P2O5) were increased from 0.3 – 0.6 – 1.2 g per pot (5 kg of soil – Mitscherlich pots). Nitrogen was applied in the form of CAN (27 % N) at a rate of 1 g N per pot in all the treatments incl. the control. Using statistical analysis, significant differences were found between the two soil types both in terms of the postharvest soil P content and yields of aboveground biomass. The content of post‑harvest soil phosphorus increased significantly with the applied rate (96 – 141 – 210 mg/kg in chernozem and 128 – 179 – 277 mg/kg in haplic luvisol). Dry matter yields of the aboveground biomass grown on chernozem were the lowest in the control treatment not fertilised with P (38.97 g per pot) and increased significantly with the P rate applied (46.02 – 47.28 g per pot), although there were no significant differences among the fertilised treatments. On haplic luvisol phosphorus fertilisation was not seen at all, demonstrating that the weight of the biomass in all the treatments was balanced (48.12 – 49.63 g per pot).

Phosphorus Application

Du Puits and Ladak varieties of alfalfa were grown for 10 weeks in the greenhouse on soil-sand media controlled at temperatures of 10°, 18°, and 26 °C. P32-tagged superphosphate was applied at rates of 10 and 80 p.p.m. phosphorus, respectively. Dry matter yields and phosphorus content of the tissue was determined at the end of the growth period. Increasing soil temperature from 10° to 26 °C. caused corresponding increases in total phosphorus uptake as a result of an increase in dry matter yields as well as an increase in the percentage of phosphorus in the plant tissue. Ladak exhibited the higher yield potential although Du Puits was less affected by low soil temperature conditions and appeared capable of making better use of soil phosphorus. With the higher phosphorus application, the root-top ratio for Du Puits was greater than that for Ladak, and the maximum value for this ratio occurred at 18 °C. for each variety. P32 activity measured in the tissue indicated that soil temperature was critical in terms of phosphorus fertilization in the 4- and 6-week stages of growth.

A mathematical description is presented of the effects through time of phosphorus fertilizer application on the growth of Stylosanthes hamata cv. Verano and on changes in extractable soil phosphorus on a red and a yellow earth in the semi-arid tropics. For the five years of observations, the models used provided reasonable descriptions of both aspects. It was not possible, however, to clearly demonstrate which of two functions tested better described the decreasing effectiveness of phosphorus with time. The simpler exponential function provided as good a fit to the yield data as did the function proposed by Barrow, whilst for the extractable phosphorus data the latter did explain a significantly higher proportion of the variance, but its coefficients could not be estimated with great precision. The results show that the phosphorus requirements of such pastures on these soils are modest. Extractable soil phosporus levels of approximately 12 �g g-1 in either 0.005 M H2SO4 or 0.5 M NaHCO3 are indicated as being adequate to ensure near-maximum yields of the legume. Long-term maintenance fertilizer needs as predicted by the models are discussed.

Target Performance

Livestock rations are formulated to minimize feed cost subject to nutritional requirements for a target performance level, which ignores the potentially substantial cost of disposing of nutrients fed in excess of nutritional requirements. We incorporate nutrient disposal costs into a modified least-cost ration formulation model to arrive at a joint least-cost decision that minimizes the sum of feed and net nutrient disposal costs. The method is demonstrated with phosphorus disposal costs on a representative dairy farm. Herd size, land availability and proximity, crop rotation, and initial soil phosphorus content are shown to be important in determining phosphorus disposal costs.
