We applied this research to answer these questions:
1-How effective is the iron rust solution as liquid fertilizer on plant growth?
2-How much is the concentration of essential elements when using an iron rust solution as a liquid fertilizer?
3-How are the soil properties affected when using an iron rust solution as liquid fertilize?
This research was applied in Oman(Ibra)in the North Eastern Governorate,we used an iron rust solution as a liquid fertilizer and mixed it with the soil,then we measure the growth of the tomato plant and compared its growth with another tomato plant in soil free from the iron solution by applying the land cover.
We sent two samples(water-iron rust solution)to the soil and water research center to find out the focus of the major elements of plant growth
We also made a comparison between the soil samples taken from agricultural land,one of them contains an iron rust solution and the other is free from the solution and compared the properties of the two samples by applying the soil protocol(acidity,Quantity of calcium carbonate,roots and rocks)
The results showed the rust solution had a negative effect on plant growth.The growth rate of tomato in the soil free from rust solution(0.75cm)compared to its growth rate in soil with a rust solution(0.325cm)
Also,this solution lacks the essential elements of plant growth compared to water rich by these elements.
Also,we concluded the iron rust solution increases the acidity and salinity of the soil compared to the soil-free from this solution its acidity decreases and approaches the equivalent nature.
On the basis of the research results,the researchers recommend not to use an iron rust solution as fertilizer because of ion(Fe3+)that not dissolved in water(chemistry book grade12)so the plant tissues cannot absorbed it and closes the soil pores (Jubouri,2018).
