“…However, further increases in P application did not increase tomato fruit yield (Mishra and Singh, 2006). Zhang et al (2007) also found that on calcareous soils, increases in marketable fruit yield with added fertilizer P were only observed at low soil P levels (i.e., Olsen P < 50 mg kg −1 ).…”

Agronomic and economic assessments of response of processing tomato (Lycopersicon Esculentum Mill.) to nutrient application with drip fertigation are essential to optimize soil fertility management that maximizes farmers' profi tability in a sustainable manner. A fi eld study was conducted to evaluate the yield and economic responses of drip fertigated processing tomatoes to additions of fertilizer nitrogen (N) and phosphorus (P) from 2003 to 2005. Th e experiment was arranged in a factorial design with four levels of fertilizer N (0, 120, 240, and 360 kg N ha -1 ) and three levels of fertilizer P (0, 100, and 200 kg P 2 O 5 ha -1 ). Fertilizer N application aff ected biomass yield of stems and leaves, total and marketable fruit yields, N use effi ciency, and N agronomic effi ciency. However, neither P application nor the interaction between fertilizer N and P infl uenced these variables. Nitrogen use effi ciency and N agronomic effi ciency decreased with increases in fertilizer N rate, with N use effi ciency averaging 443 kg kg -1 and N agronomic effi ciency averaging 237 kg kg -1 . Both fruit yields and net economic returns responded quadratically to the fertilizer N rate, with a maximum marketable yield of 127 Mg ha -1 averaged across the 3 yr. Th e fertilizer N rates were 271 kg N ha -1 for the maximum marketable yield and 265 kg N ha -1 for the optimum economic yield. Th ese values are considerably greater than the current recommendation, due to the largely increased yield with drip fertigation. Fertilizer N should be applied at an increased rate for processing tomatoes with drip fertigation to maximize the economic return.

“…(2005) found a significant increase in lettuce yield with application of P fertilizer to a soil containing 54 mg Olsen‐P/kg. Zhang et al. (2007) showed that 50 or 82 mg Olsen‐P/kg was necessary to achieve 85% or 95% of maximum tomato yield, respectively, on calcareous soils.…”

Due to the high economic value of vegetables, farmers in China often apply more fertilizer than is required for plant growth. This leads to phosphorus accumulation in soils, which can pollute the aquatic environment. This conflict arises because vegetables often use nutrients inefficiently, and require high phosphorus levels in the growth medium. In this study, amaranth (Amaranthus mangostanus L.) was grown in soils with 14.7, 23.8, 45.3, 54.6, 74.2, 101 or 116 mg Olsen-P ⁄ kg, and with and without phosphorus fertilizer (175 mg P ⁄ kg or equivalent to 385 kg P ⁄ ha). The yield of amaranth was positively correlated with soil Olsen-P content. CaCl 2 -P content was positively correlated with Olsen-P content and CaCl 2 -P markedly increased at Olsen-P contents exceeding 53.8 mg P ⁄ kg in the pot experiment or 55.9 mg P ⁄ kg in the field survey. These values were regarded as the 'change points' for phosphorus loss; to achieve 85 or 95% of maximum amaranth yield, the amaranth crop required 91or 101 mg Olsen-P ⁄ kg soil, respectively, and application of 175 mg P ⁄ kg was still able to significantly increase amaranth yield at an Olsen-P level of 74.2 mg P ⁄ kg soil. These results indicated that the phosphorus requirement of amaranth exceeded the 'change point' (53.8 or 55.9 mg Olsen-P ⁄ kg); the C min (minimum concentration in the media at which no net influx occurs) of phosphorus for 3-week-old amaranth was 1.55 lm. This value is much higher than that reported for other crops, and may explain the inefficient P use of amaranth. The high C min value also indicates that the phosphorus requirement of amaranth is beyond the 'change point' of P loss.

“…There are more vegetable‐ and fruit‐producing species than crop species, and some of them are not typically planted. In China, only a few studies have paid attention to the critical levels of soil available P required for vegetable and fruit production (Zhang et al, 2007; Liang et al, 2009; Zhang et al, 2011). Vegetable‐ and fruit‐producing species often have a higher soil Olsen P requirement than most crop species because of their small root systems, whereas the higher soil Olsen‐P requirement for fruit‐producing species is mainly caused by the large P demand and low root density, as in the case of apple ( Malus pumila Mill.)…”

Management Strategies to Optimize Soil Phosphorus Utilization and Alleviate Environmental Risk in China

In the last decade, crop production in China has dramatically improved due to greater phosphorus (P) input. As P fertilizer application rates increased from 88 to 123 kg P2O5 ha−1 yr−1 during 2004 to 2014, total P use efficiency (total P output in crops as a percentage of total P input) dropped from 68 to 20%, leading to an accumulation of >90 kg P2O5 ha−1 in the soil each year. Phosphorus lost from agriculture is the second greatest contributor to waterbody eutrophication in China, accounting for 25% of total P losses in 2010; the main contributor is livestock husbandry. Given these problems, as well as the finite nature of P reserves, three strategies are proposed here to reduce P fertilizer application rates, improve P use efficiency, and minimize the environmental risk caused by P loss in China: (i) improving soil legacy P utilization by modifying cropping systems, rhizosphere management, or microbial engineering, (ii) increasing P use efficiency by reducing P fertilizer applications and minimizing P fertilizer fixation, and (iii) promoting the extension of soil P management strategies. For these management strategies to succeed in China, close cooperation should be established among farmers, scientists, and governments in the future. Core Ideas The low P use efficiency of crop leads to >90 kg P ha−1 accumulation in soil each year. Soil P loss is the second dominant contributor of Chinese waterbodies eutrophication. Three strategies are proposed here to reduce the P fertilizer application rate. The conversion rate of scientific and technological achievements should be further coordinated.
