A soil amendment substance-organic bio-stimulator, Terralyt Plus (TP), was used to observe its impact on the properties of clay loam (CL), sandy clay loam (SCL) and sandy loam (SL) soils and the growth of corn (Zea mays indentata L.) and wheat (Triticum aestivum ssp./vulgare Vill. v. lutescens) under greenhouse conditions. The diluted TP solutions (1:500, 1:1000 and 1:2000) were sprayed onto the soil surfaces. The wheat growth increased for CL and SCL with the application of TP at 1:1000. The highest dry weights were detected with 1:500 TP and corn in all the soils. Penetration resistance of CL containing corn increased with increasing TP concentration. TP was also effective in improving the aggregate stability for CL but not for the other soils. Catalase enzyme activity (CEA), soil evolution (SE) and the total aerobic bacterial population (TABP) were significantly increased (P<0.05) by spraying TP at 1:1000 onto CL.
一种土壤改良物质——有机生物刺激剂Terralyt Plus（TP），被用于观察其在温室条件下对黏壤土（CL）、砂质黏壤土（SCL）和砂壤土（SL）土壤性质以及玉米（Zea mays indentata L.）和小麦（Triticum aestivum ssp./vulgare Vill. v. lutescens）生长的影响。将稀释后的TP溶液（1:500、1:1000和1:2000）喷洒在土壤表面。对于CL和SCL土壤，施用1:1000的TP后小麦生长有所增加。在所有土壤中，1:500的TP处理下玉米的干重最高。含玉米的CL土壤的穿透阻力随TP浓度增加而增大。TP对改善CL土壤的团聚体稳定性有效，但对其他土壤无效。通过向CL土壤喷洒1:1000的TP，过氧化氢酶活性（CEA）、土壤演变（SE）和总需氧细菌数量（TABP）显著增加（P<0.05）。
