How Much Does Soil Type Matter To Crops? 

This is the question Year 3 and 4 are investigating at the moment.  Using time lapse photography and our loyal light bank to observe the development of a range of crops we hope to find the answer soon!

We have been amazed at how quickly the seeds have germinated (3 days) and how healthy the young plants are looking so far.

We have chosen the ancient ‘Kamut’ wheat, modern wheat, field beans, oil seed rape and Sorghum, which is grown in very hot countries!  The soils we have chosen are, home made compost! , pure sand, garden loam and a clay soil from a river bank.

The Results Are In 

Thank you to all the children working hard to carefully measure our plants after 6 weeks of setting up the crops growing in sand.  The results make very interesting reading and do answer our question. Yes, soil type does make a massive difference highlighting that different crops prefer different soils.  The wheat grew very badly in the sand with half the leaves dying, on the other hand Sorghum, the tropical crop, preferred it above all other soils!  The beans also did well in sand.  What conclusions can you draw from our results?

In a final analysis class 4AR concluded that from this experiment they found that the soil type really does matter with different crops preferring different soils. They calculated that Sorghum was more than 3 times taller in the sandy soil compared with the compost, no doubt due to it being adapted to the very hot and dry conditions it’s used to in the plains of Africa, Asia and parts of America where it is normally grown. It was also really interesting to note that Sorghum was the only crop that didn’t wilt over the half term holidays when all the others suffered due to a lack of water. The field beans were by far the tallest plant, growing more than 50cm.

We look forward to improving on this experiment and repeating it in the near future…





Halloween Harvest

Our 3 Sisters experimental plot has developed many nice surprises over recent weeks.  How many different seed pods and fruits can you find in our garden at the moment?  

Many classes have been learning about plant life cycles throughout the school and have enjoyed exploring our gardens to learn more over the past few weeks…

Well done to members of year 6LH and 6AK who took many of these images to capture the life cycle of many of our school plants.  We can’t believe our eyes seeing strawberries fruiting again  in autumn!
