2011), however, the negative influence of heavy metals and environmental hormons

that should be evaluated (Kelessidis and Stasinakis, 2012). This study was conducted

to evaluate irrigated water that was insteaded of livestock liquid to produce the liquid

fertilizer. On the other hand, after application, the effect of different liquid fertilizers

on tomato and waxapple were compared. In this experiments, the circular agriculture

and appropriate fertilization will be achieved.

Materials and method

Experimental design and production of liquid fertilizer

This experiment was designed for the production of liquid organic fertilizers by

livestock liquid. The materials were used as below, the drainage water (or livestock

liquid) 300 liter (L), soybean powder 9 kg (kilogram), rice bran 9 kg, phosphate rock

powder 9 kg, seaweed powder 9 kg, molasses 18 kg and fermentating microbiology

3 kg. The hydrolysis of soybean by will produce high polypeptide and amino acids

and then serve abundant nitrogen fertilizer to plants (Kanu et al., 2009; Zhao et al.,

2012). phosphate rock powder (tricalcium phosphate) is commonly a kind of

phosphorus fertilizer in the phosphorus source in fertilizer (Xu et al., 2019).

Vijayakumar et al. (2018) showed that application of a lower concentration (20%) of

seaweed liquid fertilizer (SLF) will increase fresh weight, leaf area, protein,

carbohydrate and lipids of Capsicum annum L. Hence, the seaweed was used to

supply the potassium in liquid fertilizer. The productive methods were as follows. At

first, the 300 L plastic barrels were prepared, and the groundwater (or fermented

livestock liquid) and prepared materials were all put into the barrel. And the the

liquid fertilizer were stirred by electric stirrer two times every day for 14 days. The

stirring duration was 5 minute every time. After 30 days, the crop experiments were

proceeded. The experimental designs were described as Table 1. The tomato (CK, CF,
