Field 6 Riuskanoja

Basic information about the field

Area: 8,56 ha
Soil type: Hummus rich sandy loam, hummus rich sand moraine

The soil type is varying in different places on the field. West end had heavy clay and east end had light sand moraine. The different soil types are affecting the choice of proper sowing time. The shape of the field is good. On the east end there is a separate “horn” (0,13 ha), which is cultivated as nature conservation field. There is a long term weed observation research going on in the field, where the amount of weeds and their affect on the yield is observed by using different kinds of mechanical control methods.

Here you can also read the information card on organic mixed farming produced by Natural Resources Institute Finland:


A: Recycling fertilisation test
Varietal: Feedway, 256 kg/ha
Sowed: 8.5.2023
Fertilizer: Yarasuna 10-4-1
Square 1; 0 kg/ha
Square 2; 600 kg/ha
Square 3; 800 kg/ha


B: Fava bean and oat -line experiment
The experiment investigates the effect of different alloy ratios on crop security. The experiment has four different lanes in two repetitions.

During the growing season, the density of twigs, side shoots, weeds pcs/m2, the height of the canopy and the beginning and end of flowering were observed in the experimental plots. The broad bean was taller in the pure crops than in the mixed crops, and the oats in the pure crops were shorter than in the mixed crops. The number of cracks varied a lot in the experimental area and no clear difference between pure and mixed vegetation could be seen. The quick wheat colonies and bedstraws that hit the experimental area made it difficult to observe the breaches.

Here you can see test results

The last observations from the lanes were made on August 16

C: Protein plant + grain -line experiment
The experiment investigates the effect of different alloy ratios on crop security. In the lanes grow plants of two plants which have sowed with ordinary seeding machine by using seed and through fertilizer hoops.

During the growing season, the density of twigs, side shoots, weeds pcs/m2, the height of the canopy and the beginning and end of flowering were observed in the experimental plots. Also in this experiment, the weed colonies that hit the spot, such as sedge and common wheat, made it difficult to make weed observations, so a clear difference between the mixtures could not be observed. In the broad bean-oat mixture, both broad bean and oats grew taller than with other plants.

Temperature curves from the field. Green is temperature of the air, orange soil temperature from 20 cm depth and blue 50 cm depth.

The soil moisture from the same place, the graph is showing values in kPa in different depths (20 cm and 50 cm). Most significant change has happened on 17.6., when the soil has clearly dried in 20 cm depth. In 50 cm depth, the change has been more moderate (luckily).

KM yield competition

Mustiala’s teaching and research farm is participating to KM yield competition with wheat Helmi. The competition area is on the east edge of the field, but the more precise area of 1 ha will be determined closer to harvest.

2.6.2020 KM yield competition filed as VARI-index image. The more green color, the more growth. At the moment, it seems that the best areas would be on the lower edge of the area, on the right and on the upper corner on left.

230620  In the competition area, the greenest parts are changing as the growing season is going further. Now the picture has been cropped to show only the area flown.

230720 Picture taken from the competition field, which has been modified with Pix4D-program. Still the middle part of the east edge is giving best place for the competition
Kuva1: filtered for blue color and bw-image from it. Couch grass places can clearly be seen in the growth.
Kuva2: picture showing the amount of color green
Kuva3: normal colored picture shown in dot cloud
Kuva4: filtered with multiple colors
Kuva5: filtered only with two colors; green is showing good growth and purple worse
Kuva6: filtered with 20 different colors. Picture gets more precise, but does not give extra value for interpretation.
