AZOMITE® Peach Study


Peach Farmer's Association, Yangshan, Wuxi, China, Nov. 2004

The use of environmentally friendly ingredients with low toxicity in international agricultural trend. AZOMITE® is a multi-mineral fertilizer that is OMRI-listed for certified organic production in the United States. An experiment was conducted in 2003 to test AZOMITE® ‘s practical application in China.. The crop selected was the Peach from YangShan District of WuXi City, Jiangsu Province, China. Peach from this area is well known in the nearby provinces and supply major markets such as Shanghai, Nanjing, and HangZhou. There are over 100,000 Mu (6600 hec.) of peach farms in the area, with an annual production of over 100,000 tons of peach between May and August. The objective of the test included the effect of AZOMITE® on peach trees under stress; due to old age or or depleted nutrients in the soil.

2 Material and Methods

2.1 AZOMITE® (Peak Minerals, Inc. USA) was provided from Shanghai Lytone Biochemicals, Ltd. And its main ingredients included 67 different elements, as stated from the original supplier. Potassium sulfate was purchased from commercial sources.
2.2 Experiment Design: A total of 12 lots were selected at random to divide into 3 different groups. Each group will have 3 lots
as replicates with 0.5 Mu (333 M2) each lot. The three groups are:
A. 3KG AZOMITE® spread around the root crown of each Peach Tree. Approximately 150KG were used for each Mu.(Ave. 50 trees/Mu). Additionally, 5KG organic fertilizers were used per tree;
B. 3KG of a commercial chemical fertilizer was used instead of AZOMITE® . 5KG organic fertilizer was also used;
C. Only 5KG organic fertilizer was used for each tree
2.3 Location: All of the lots were located in Yangshan Village, Yangshan Township.
2.4 Plants: All of the Peach trees were locally grown since late 1970s. There was some seedling improvement effort. However, the farmers seemed to rely solely on the government extension station's help in strain improvement.
2.5 Land: The fertilizer strength of the soil in question were of average, with a rather flat layout. There was no significant differences in soil condition between the groups
2.6 Season: The fertilizers were all applied on Nov. 15, 2003 according to plan, and covered lightly with soil. There was no significant weather condition that could have impacted the results of the trial. The management practice of the farms were also identical.
